You don’t have to prepare a “dish”. Pair any protein with any carb with any greens, and just eat them on a plate, e.g. pasta tossed in olive oil, grilled fish, and some random root vegetables grilled in an air fryer. It doesn’t have to be coherent to be tasty or nutritious!
If you have a protein target to hit, don’t be afraid of consuming high amounts of protein powder (up to half of your daily intake), provided that it is free of heavy metals, and you’re eating a well balanced diet. Protein powder is convenient, cheap, and helps to reduce meat intake.
