First, to V02, chicken isn't ALMOST as high in protein as beef, it's HIGHER! 😄 Well, OK, that's if it's breast... almost all protein, very little carb or fat.
Anyway, the original poster asked about quick meals. Here's tasty and quick...
Precook a bunch of your favorite pasta. The whole box/bag/whatever. I'm thinking rotelli or some other thick kind, not spagetti or linguini. Stick it in the fridge.
When you are ready to make something, put it in a microwavable container. Add some flax or olive oil (don't be afraid of some fat!), some sliced or chopped zuccini or other squash, parmesan cheese, maybe a little gorgonzola cheese, maybe some sliced olives, and any other finely chopped veggies you like. Nuke it until it's all hot. Stir a few times. This whole thing takes <5 mins. Add chicken for protein, or even some cottage cheese. Sounds insane, but it actually works well.
