Meat, veggies, fruits, tubers, dairy.
Nut flours aren't that great anyway. I think a worthy egg substitute is a mashed banana in some recipes... you can look up baking substitutes for eggs too (avoid the "flax egg"). Maybe try cottage cheese or full fat greek yogurt as "egg" in recipes?
Breakfast: I find dairy(cottage cheese, yogurt)+fruit, or jerky, to be extremely satisfying. You can also get coconut chips either dried or fried in coconut oil! A smoothie is also great.
Instead of nuts, snack on fruit/jerky/sweet potato chips/coconut chips...or better yet, don't snack at all and just eat meals.
Look into stews, curries, stirfries, roasts, and BBQ's of various nations. These aren't based around nut flours/nuts or eggs.
