Recipe ideas

So I currently have a calorie allowance of 2279 calories a day. I am doing very well with staying under budget, but am bored of the same meals all the time. I work nights and don't have a lot of time for meal prep and elaborate meals. I am looking for any quick recipes that you might recommend.

Currently I'm eating a lot of egg and vegetable scrambles, fish (mainly flounder, shrimp, or scallops cause they are versatile), chicken, and vegetable dishes. I've found that I can make a low calorie chicken fried cauliflower rice, but I need some more variety.

I am looking for anything that is quick (under 20 minutes), low calorie, high protein, and the ingredients don't cost a lot of money (crab, lobster, dragon fruit, stuff like that.)
