Spread your tomatoes on a baking sheet, drizzle with olive oil, and roll the tomatoes in the oil so they're all coated.
Sprinkle with salt and pepper.
Bake for 15 to 20 minutes. (15 minutes is the sweet spot for my oven.) You'll know they're done when you see the skin crinkle and separates some from the tomato flesh.
Remove from oven. Enjoy as is or add to pasta, salads, omelets, and more!
