You could probably make a homemade spaghetti sauce. (Tomato puree, onions, italian seasoning, garlic powder, salt, oregano, possibly some hamburger meat if you want a meat sauce.)

Homemade pasta. (If you want a more fresh version than the boxed stuff -- super easy to make. Flour, a bit of salt salt, eggs.)

Homemade italian bread. ( EDIT - Nope, you're missing olive oil. You could probably do a white bread/dinner roll, though. Flour, sugar, yeast, eggs, salt.)

I'd give you actual recipes, but I can't. (My recipe box is in storage at the moment. D:)
