Preheat oven on broil
Add fresh, washed cherry tomatoes, onion and jalapeños to a baking sheet lined with parchment paper.
Spray everything with olive oil and add to the broiler for 10 minutes.
Combine everything in a food processor, including the juices, and blend. You can do this in parts if the food processor is small.
Add to an airtight container and refrigerate at least three hours. Ideally 6 -12 hours.
Add in the salt, pepper, lime juice, garlic powder, garlic salt, oregano, cumin and cilantro. Mix well and then enjoy.
Store in an airtight container in the refrigerator for up to 4 weeks. If you want to keep it longer than that I recommend canning.
