One way to make cherry tomatoes taste good is to roast them in the oven. 1) Apply to preheat your oven to 350 degrees F. Then, line a baking sheet with parchment paper and lightly brush the tomatoes with olive oil. 2) sprinkle them with salt and pepper, and then bake for about 20 minutes or until they are soft and slightly browned. You can also try adding them to salads or sandwiches for a delicious and nutritious snack.
