For me its usually some kind of doctored up ramen. Peanut noodles, spinach and cheese added, etc. Or just some kind of quick "pasta and whatever" meal (usually leftover sauce and dried/frozen veggies or chicken broth/lemon/garlic/parmesan dumped in the pot)
my cheese ramen usually constitutes of cooking it with some frozen spinach, draining most of the water, and then adding the seasoning + shredded cheddar cheese
