i do a few that i love but one of the easiest is lemon brocc pasta: rotini (or penne), head or two of broccoli, loooots of spinach, lots of minced garlic (store bought is ok!), few tbsp lemon juice to taste, pinch of salt and pepper, ample parmesan
pasta obv takes a bit but thereās basically no prep. if you really wanna save more time/energy literally just get microwave broccoli/chopped spinach instead of fresh lol. and if youāre cooking for one, an entire box of pasta will make quite a few meals for your next lunches and dinners, and it microwaves well! so you get the home cooked meal vibe for a few days without too much work
