What are some cooking ingredient staples?

My friends and I just moved into our new apartment and we’re about to embark on the adventure of cooking for ourselves every day. We’re making a grocery list of ingredients to buy and I could use some suggestions.

So far, we have: herbs, breadcrumbs, spinach, potatoes, onions, garlic, shallots, carrots, olive oil, soy sauce, cheese.

What are some ingredients that are widely used in a lot of recipes? I’m looking for generic, simple ingredients, nothing specialised or fancy. Thanks!
