Tomato-Chipotle Coulis

2 large, round tomatoes or best available
2 garlic cloves, minced
1/2 white or Spanish onion, minced (Torres says the white onion is more commonly used in Mexico)
1 chipotle en adobo, from a can (I used half of one and thought it had a plenty-big kick, you can always start with a quarter and add more if desired)
Kosher or sea salt to taste

Migas
2 links Mexican or Spanish chorizo, removed from casing, diced or coarsely chopped
4 tablespoons oil (a mixture of corn and olive oil works best)
8 eggs, lightly beaten
20 corn tortilla chips, preferably fresh
Fresh cilantro for garnish
