I mean shit like lentils, couscous, quinoa, chickpeas, seeds in general, canned beans, dont spoil and cook easy and fast. They are all varying degrees of recommended meat replacements (not full but at least partial, especially lentils and beans) Same with frozen spinach and frozen vegs.

Taste will have to be added, i mean enhanced, with oil, herbs, spices, balsamic vinegar, tomato sauce, etc
