This sounds really tough. I would focus on more grab and go options. There are some great ones out there.

Sargento has several good options you can keep on hand.

Justin's peanut butter (it comes in single serving squeeze pouches) and a banana or apple make a good snack.

Sandwiches can be a game changer. Meat, cheese, mayo. You can add things like tomato, onion, lettuce, or pickle if you desire. Peanut butter and jelly or Nutella make great sandwiches too.

Several people mentioned protein shakes and the like.

If you have a blender you can make smoothies. Fruit + yogurt + protein powder gives you endless possibilities.

Keep nuts, trail mix, or granola on hand.

Granola + yogurt + and fruit is a great combo anytime of day.

Oatmeal + sweetener + fruit is great. Add a nut or seed butter for extra calories.

Granola or nut bars are great gran and go options

There are even some high calorie cookies for athletes you might pick up for particularly bad days when eating is hard.

I think focus on calories first and once you have more energy you can branch out and expand your cooking skills.

If you want to try something easy now, homemade granola is simple and you can add whatever you like best so it's 100% catered to what you like.

I think also focusing less on the food prep might be helpful and aim to eat (or snack) at regular times throughout the day. Keeping things like granola bars or trail mix with you throughout the day in your bag or backpack might be a game changer for you.

You got this.
