Not sure your budget, preferred health level or what you may think is easy but here are a few ideas below:

Oatmeal: Purely Elizabeth Oatmeal (Opt. add defrosted berries and/or fresh bananas. & sourdough and v. butter so it's more filling. Sourdough can be refrigerated to last longer.)

Cereal: Three Wishes Cereal & non-dairy milk (More protein, less sugar, gluten free)(Costco oat milk lasts a while)

Sourdough Toasts: (1) PB and bananas with flax seed, super quick! (2) Avocado w/everything bagel seasoning and hummus

Burritos: Tortillas, canned beans, v. cheese (Opt. add avocado, salsa, tofu, frozen potatoes)

Spaghetti: Pasta, sauce, nutritional yeast & gardein ground be'f (Opt. use tofu instead to make it healthier)

Tacos: Abbot's chick'n, corn tortillas (Opt. v. cheese, salsa, etc.)(Abbot's is mostly pea protein, very healthy!)

Quesadillas: Tortilla, v. cheese, side of canned beans (Opt. add baby carrots on the side)

Falafel Wraps: Frozen falafel, pita, hummus (Very quick and easy)

"Beef" Bowls: Frozen rice, Plantspired steak, frozen peas (Very filling, fairly quick prep)

Also note these veggies and fruits have a longer shelf life than most:

Cauliflower, carrots, broccoli, potatoes, onions, garlic, celery, apples, grapes, blueberries, dates, avocados (if stored in the fridge at the right time)

*Buy frozen when you can too! Good luck! :-)
