Preheat oven to 450°F.
Prepare the Tomatoes, Peppers, and Onion: Remove the stems from the tomatoes, rinse and scrub thoroughly under cool water, and then cut them each in half lengthwise. Trim the stems from the peppers, cut them in half lengthwise, and scoop out all of the seeds using a small spoon with a relatively sharp edge. Trim the ends from the onion, peel the outer layer of skin, and then cut it into quarters.
1 ¾ lbs. tomatoes, 1 medium onion, 1-2 jalapeño peppers, 4-6 garlic cloves
Roasted Vegetables in Oven: Place the tomato halves and jalapeño peppers skin side-up onto a large baking sheet along with the quartered onion and garlic cloves. Drizzle oil over all of the vegetables and rub it into their skin. Roast the vegetables in the preheated oven for 25-30 minutes, or until the tomato skins begin to brown. Pull the garlic cloves out after 15-20 minutes to prevent burning.
2 Tbsp. oil
Pulse Ingredients in Processor: Add the roasted tomatoes, onion, jalapeño, garlic cloves that have been peeled, and any oil on the baking sheet to a large food processor along with the remaining ingredients. Pulse ingredients 10-20 times and then scrape down the sides of the bowl. Continue pulsing until the salsa reaches your desired consistency. (About 40-50 times.) Do NOT puree. You'll end up with a watery salsa!
½ cup cilantro leaves, 1 Tbsp. lime juice, 1 tsp. salt, ½ tsp. paprika, ¼ tsp. cumin, ¼ tsp. black pepper
Serve roasted tomato salsa immediately or store in the refrigerator for up to 24 hours for an even better flavor. Salsa will keep well for up to 4-6 days when stored in an airtight container in the refrigerator or up to 2-3 months if frozen.
