Gluten free and low cal?

I do greek yogurt with different combinations of flavours (fruit, cocoa powder, maple syrup, peanut butter, protein powder, etc) on most days. Banana with peanut butter. Omelets. Some brands of oats are gluten-free if you tolerate oats. I mash together a banana and 2 eggs and baking powder, add desired flavours for flour free pancakes. You can buy all-purpose gluten free flour to make muffins.

For bread, I like Udi's millet-chia. It comes frozen, and I just defrost the portion I want. Gluten free bread usually doesn't have preservatives, so unless you're gonna eat it every day, it will last lomger in the freezer. Two slices are 150 calories. Hot cereal is filling. Glutenfreeda has instant oatmeal made with certified gluten free oats. Tasty and 190 calories per servimg. For only 131 calories per serving, there is Ancient Harvest quinoa hot cereal flakes. If you're not into eggs, maybe try yogurt? Chobani plain nonfat Greek yogurt is gluten free. One cup is 120 calories or so. I like to add some fruit to it and a bit of stevia. I just get store brand frozen fruit and defrost a measured portion; I like raspberries, blackberries and cherries. For cold cereal, I like KIND peanut butter whole grain clusters. Watch the portions, though: while a half cup serving has 10 grams of protein, it also contains 210 calories. One more idea: Van's gluten free ancient grains frozen waffles. Two waffles contain 210 calories. I heat them in my toaster (make sure you use one that has NOT ever had wheat-containing items in it) and then microwave them at medium heat for about 30 seconds to soften them a bit. I don't put anything on them as they are flavorful enough plain. They contain a little protein, but I'll have some reduced fat cheese with it to bring it up to a full serving of protein.

I eat porridge oats made with boiling water most days. Measure out the oats (i love gf jumbo oats), mix in a dessertspoon spoon of sultanas, 1/2 tsp of cinnamon, and a tsp of honey. Cover with boiling water and leave for about 5 mins. So nice, and keeps me full for a long time

Aldi carries GF wraps that are only 110 calories each. I know you don't really care for eggs, but how about a frittata with a lot of vegetables - I like mine with cabbage and bacon.
For other meals I eat a lot of stews, chilis, soups, stuffed peppers, meatballs, nuggets (I pulse corn chex with spices for breadcrumbs and keep on hand). Basically I just cook a bunch of dishes, portion and freeze for easy meals during the week.
Quick meals like stir fry or zucchini noodles or even roasted vegetables with some kind of meat are usually our go-to dishes. Sometimes I make enchilada casseroles with corn tortillas (almost like migas or rice and beans.

I have celiac's, so every meal is GF for me! But my breakfast is generally fage 0% greek yogurt w/honey (under 200 cals) or a smoothie (pb, flax, banana, milk, low fat vanilla yogurt about 250 cals). When I have more time in the morning (i.e. weekends), it's either cereal (I'm partial to honey nut chex) or bacon and eggs.

Gotta love bacon for being gluten free!

ETA - just as a note, depending upon how sensitive you are, oats can be a problem for some people. it's ~hotly debated in the GF community, but oats and wheat are harvested together which potentially leads to cross contamination. This is more of a problem for people like me (Celiac). But if you are very concerned and want to try one of the oat suggestions in this thread, then make sure you buy oats that are specifically gluten free as they are specially harvested.

I just eat Chex cereal with some lactose free milk and honey or sugàr. Comes to around 300 calories and fills me for most of the day.

my daughter has celiac -- she does smoothies with greek yogurt & frozen fruit. Also the banana/ egg pancakes, although she adds a 1/4 cup gf flour to stabilize it. GF cereal, mixed with yogurt instead of milk -- more protein. GF toast with a little peanut butter or cream cheese (or make a sandwich with deli meat, just check to make sure it's gluten free!!). Quest / Kind / or other protein bars with a piece of fruit if she's in a rush. Protein shakes -- she uses slim fast, again for busy mornings (college student). Also eats eggs, but she likes them. Toufani (sp?) brand makes gf wraps that are tasty (according to her) AND are shelf stable & flexible (not thin/don't break easily like some others).

Read the wheat belly by Dr William Davis Cardiologist. It isn't just gluten that we are allergic to, its gliceride as well. All grains and flours need to be eliminated completely. I'm on 30 days and down 10 lbs
