Spread tomatoes on baking sheet. Drizzle with olive oil and sprinkle on salt and pepper. Toss tomatoes to coat.
Roast for 15-20 minutes until tomatoes are soft and blistered.
Notes
Any kind of smaller tomatoes like cherry, grape or Campari tomatoes will work great. I used heirloom cherry tomatoes. I love the mixed colors! You can also use larger tomatoes like Roma tomatoes. However, the cook time will need to be a little longer to account for the larger size. After 15 minutes, watch your tomatoes closely as they bake and be sure you don't burn them. Roast in 5-minute increments.
