I guess what I’m looking for are more minimalist options for approaching food prep.

Are you familiar with Soylent? It's similar to what they feed coma patients. 400 calories per serving, plus a full set of macro & micro-nutrients. Kind of like a protein shake, except it's a whole meal in a drink. They have a bottled version, which is shelf stable, and is available on Amazon, as well as places like Target, CVS, etc. (the 12-pack works out to just under three bucks a bottle, at current prices). Zero effort, zero dishes, 100% nutrition:

If you want to cook, do you have access to boneless, skinless chicken thighs? You can use it in a variety of ways:

1. As a chicken breast
2. As a chicken cutlet, where you pound it down flat (plain or breaded & fried)
3. As chicken strips
4. As shredded chicken

You can dress it up in a variety of ways:

1. With a spice rub
2. With sauces
3. With cheese melted on top (ex. broiler function in the oven)
4. Breaded & fried (pan-fried in a skillet or deep-fried in a pot)

When I was new to bodybuilding, I didn't understand macros at the time & didn't really know how to cook, so I pretty much lived off oatmeal, eggs, brown rice, chicken, and broccoli. It wasn't a super fun way to eat, but I felt great all the time & it was pretty dang cheap, haha! Plus I learned how to doll up the food using spices, sauces, and so on, in order to create variety.

How are you cooking skills right now?

did you jerks (kidding) buy all the cacoa already?
