I don't know about "typing" in what you have & getting a magic answer. But I do think one should be able to make nearly a week's worth of meals with what's in the pantry, fridge, & freezer. It's all in the planning.
I always have quite a few boxes of different types of pasta on hand, along with crushed & diced tomatoes, jarred tomato sauces, etc. Also wouldn't be without a variety of canned beans. Also always have a full spice inventory, especially things necessary for an Asian stirfry.
Always have basic cheeses like cheddar & swiss in the fridge, along with salad fixings & fresh vegetables that last well, like broccoli, cauliflower, carrots, etc.
With a freezer full of individually frozen boneless, skinless chicken breasts; ground turkey; turkey/chicken sausages, raviolis, etc., if I can't get to the store for a few days, I can certainly make quite a number of different dishes without feeling deprived.
