snack ideas

I generally stick with the good ol' boiled egg or some form of cracker with all natural peanut butter, but these are higher in fat snack, but they are healthier than naughty high processed snacks. Maybe also try air popped popcorn too. These are my go to snacks, besides almonds and fruit that is

I like almonds or a greek yogurt.

Low-fat yogurt. Greek is esp. good because it's higher in protein. Some fat is good because it makes you satisfied, which nonfat doesn't do so well.
Hard boiled egg
A piece of whole-grain bread with a tablespoon or 2 of peanut butter, and a glass of milk
A piece or two of deli meat (I like turkey) rolled with a slice of cheese
A stick of cheese + 1 or 2 servings of Keebler pita chips
A piece of swiss cheese
Fruit
Nuts
Baby carrots, strips of bell pepper (I like red & yellow), florets of broccoli & cauliflower. (Take a tiny tupperware with some ranch dressing for dipping.)
Olives

For fast but not so portable:
A bowl of instant oatmeal with fruit &/or nuts
Cottage cheese. Sometimes I like to stir in sunflower seeds.
Pan-fried dumplings. Takes about 7 minutes, and the ones I buy are listed here as 8 pieces for 260 calories.
A tortilla (relatively high in calories) with nonfat refried beans & 1/8 c of shredded cheddar, heated in the microwave, then topped with salsa & salad & rolled.

Greek yogurt
Cottage cheese (they sell individual cups)
Larabar or Clif bar
String cheese + almonds
I know you said you already do veggies & hummus, but that's a favorite of mine
Beef jerky
Banana + peanut butter (they sell individual cups of pb)
Trail mix

I like trail mix. I make it and bag it. Raisins, nuts, sunflower seeds, and maybe throw in a fruit like blueberries. A little salt if you don't get too much of it elsewhere. But it is a lot of calories, best to weigh and measure out each baggy.

A couple of sea salt crisps from Trader joes are the bomb!
Apple Slices with Peanut Butter (and a little strawberry jelly mixed in)
Pretzel with hummus
the whole wheat flax 100 cal sandwich thins with some lettuce and tomato in it, its low cal.
Freeze Dried Banana
Banana Chips
Kashi Cinnamon Cluster Cereal, Can mix some with a little popcorn in a baggie and yum!
