Nut-free healthy snacks and quick breakfasts?

My go-to breakfast is baked oatmeal - I have to make it the first time but after that I can just reheat each portion. I like the texture better than typical stovetop oatmeal anyway, but the convenience is also very nice. Some recipes involve nuts but the one I typically use does not, though I do add 16g of peanut butter to my portion each morning. I modify this one: https://www.budgetbytes.com/oatmeal-cookie-baked-oatmeal/ with blueberries instead of raisins and lower the butter and sugar.

Similarly, I like egg casseroles (another make it on the weekend then reheat portions) but you could also just do hardboiled eggs. If you like dairy, yogurt, cottage cheese, and cheese sticks can be higher protein options that are nice for breakfast or snacks. Hummus or baba ghanouj and veggies to dip. Or even eat dinner leftovers for breakfast!

Breakfast burritos take some time to prep but once they're made, they couldn't be easier. I've been making them for 7-8 months now so I've got it down to a science. You can use basically whatever you want for the filling; lately I've been making a filling of whole eggs (about 6), bacon, black beans, cheddar cheese, and shredded Yukon gold potatoes. I've also done sweet potatoes, that works really well with the bacon and beans. Queso fresco or pepper jack is a good sub for the cheddar. Sausage also works well for this, it's just more expensive IME.

Cook the filling all together in one big skillet: first bacon, then take that out and cook the potatoes in the bacon fat, then add everything else and mix around until the eggs are cooked. Fridge the mixture for a couple of hours until cool, then roll up a dollop (~85g) of filling in a soft-taco-size tortilla and wrap in parchment paper. Freeze overnight, will keep for at least a month. Reheat in a microwave for 1:30. 6 eggs, half a pound of bacon, about 3 medium-size potatoes, one can of beans and 4oz-ish of cheddar makes enough filling for 11 burritos, one burrito is about 330 calories (34g carbs/16g fat/13g protein). I've used the low-carb tortillas and found them more difficult to work with, quite dry and prone to breaking, and they also didn't taste nearly as good.

aside from peanut butter i dont eat nuts hardly ever.

lots of things in this world that are NOT nuts lol

eggs, bacon, sausage, toast, sandwiches, salads, cottage cheese, yogurt, fruit, my husband eats a lot of nutrigrain type bars and protein bars (without nuts), cheese, muffins, home made egg mcmuffin type things...

lots of possibilities...

Overnight oats, and there are SO many different ways to make them! Smoothies with a good amount (at least 25 grams) of protein, some healthy fats (chia or flaxseed, avocado for example), and some produce (fruit and or/veggies) are good, also. For snacks, I would sometimes grab a cheese stick and some fruit. Do you/can you eat soybeans or other seeds? Roasted soybeans and pumpkin seeds or pepitas are good, and for me it doesn't take much to fill me up.
