Preheat oven to 400.
Wash and half your tomatoes and chop your onion in fourths and place in a large roasting pan.
Cut the ends off of the heads of garlic and place cut side up in the roasting pan.
Wash, de-seed, and cut the bell pepper in chunks and place in roasting pan.
Cut jalapeno in half and de-seed and place in the pan.
Place the sprigs of thyme and basil in the pan.
Evenly coat everything with olive oil and salt and pepper.
Roast at 400 for about 45 minutes or until veggies are tender. You can cover for quicker cooking. I like some texture to my veggies so I leave them uncovered.
When everything is done remove from the oven and allow to slightly cool enough to handle the garlic.
Spoon everything but fresh thyme and garlic into a large blender. (including any juices from the pan)
Squeeze garlic out of the cloves into the blender and discard the halls.
Add a teaspoon of powdered turmeric powder to the blender.
Blend everything until you reach the consistency you like adding extra salt and pepper if needed.
Spoon into a bowl and drizzle with a little olive oil and some fresh herbs if desired.
