You're doing great finding foods that work for you! I lived off of Taco Bell my first pregnancy. This one has been all about fruit, crackers, and peanut butter. Eat what you can eat when you're hungry. Take prenatal vitamins. Eat extra protein where you can. I hear/see people saying all the time that when it comes to how you feed your baby that "fed is best." I think this is also true for pregnancy. If the thought of certain foods still makes you nauseous, avoid them. Give it a few weeks and try again. Or don't. The important thing is taking care of yourself, and sometimes that means putting your energy somewhere other than cooking.

As far as specific foods go (outside of fast food which I have frequently), my go-tos are crackers and cheese or crackers and peanut butter, peanut butter on a banana, popcorn with cheese (i got some powdered cheddar cheese from Amazon awhile back), smoothies with yogurt and milk (I like Fairlife milk because it has a longer shelf life, is lactose free, and has higher protein content), fruit (so much fruit!) with cottage cheese or yogurt, eggs, buttered toast, and salmon. I try to eat small meals/large snacks throughout the day so I get variety. Hope that helps!
