Step 1

Rinse and de-stem the tomatoes.  Roast the tomatoes in the oven at 400F for 20-25 minutes.

Step 2

De-stem and de-seed the chipotles in adobo.

Step 3

When the tomatoes are done roasting (20 minutes or so), add them to the blender along with 1/2 white onion and 1 garlic clove.  Add only 1/4 of the chipotle in adobo.  Pulse blend and taste for heat level.

Step 4

If you want more heat, add another 1/4 or 1/2 of the chipotle.  Keep adding chipotle until it tastes "right" to you.

Step 5

Serve immediately and store leftovers in an airtight container in the fridge.
