Grape tomatoes

Grape tomatoes are very small, but that doesn't mean that they aren't perfect for dicing and tossing into a salad or eating alone as a snack. If you prefer a tomato that isn't as juicy as Roma or cherry varieties, grape tomatoes may be the perfect pick for your meal prep.

Roma tomatoes

Roma tomatoes are the perfect size for dicing. Their long tubular shape makes it really simple to cut the tomatoes horizontally, and they are great for making sauces or pasta dishes. They provide a juicy and naturally sweet flavor to any meal, whether they're diced or cut into quarters.

Vine Tomatoes

Tomatoes on the vine are still attached to the vine to take one when you purchase them. This helps to extend their shelf life. These medium-sized round tomatoes can be sliced and diced and added to sandwiches, used for bruschetta, or simply canned and stored in the pantry.

Beefsteak tomatoes

Beefsteak tomatoes are great for dicing, and they also have very high vitamin C content, an immune-boosting antioxidant. They work well sliced or diced on hamburgers and sandwiches. These tomatoes have a mild and juicy taste that makes them perfect for sauce making and canning.

Cherry tomatoes

Though cherry tomatoes are small bite-sized varieties, they can be diced for salads or tasty pasta dishes.

Heirloom tomatoes

Green tomatoes

Green tomatoes are also great for dicing. They go especially well with southwestern dishes such as cornmeal, dirty rice, and jambalaya. Green tomatoes have a slightly sour and tangy taste, making them perfect for relish and other condiments.

When thinly sliced, they make for excellent add-ons for sandwiches and meats.

Can you dice tomatoes in a food processor?

You also benefit from first slicing the tomatoes in two halves before throwing them in the processer.
