Put whole tomatoes, quartered onions, garlic cloves on a pan and drizzle with a little oil. Bake until everything looks roasted. Garlic should come out first, after about 15-20 minutes or when soft.
Throw all your baked veggies into the food processor and pulse until you have the desired texture. Don’t overdo it or it will be juice!
Season to taste with salt and pepper. Add more jalapeno if you like more heat.
This can be eaten now, kept in the fridge for a few weeks, or canned. I canned it this time and it worked well! Enjoy!
