When it comes to kitchen staples, canned tomatoes are your best friend. We've all got at least one can stockpiled in the pantry, ready at a moment's notice for a last-minute pasta sauce or weeknight chili. Of course, nothing beats the big, meaty slices of heirloom tomatoes for summer Caprese salads, but for soups, stews, bruschettas, and a Giada De Laurentiis-approved ricotta dip, the canned varieties are indispensable for amping up that pure and concentrated flavor.
