Sure you could buy tortillas at the store, but they are pretty easy to make. By adding in roasted poblano peppers you get a little more flavor than a regular tortilla. Poblanos have a nice fruity flavor with just a touch of heat.
Set your oven to 400°F. Place the poblano peppers on a lined baking sheet. Roast until they start to blister, turning to make sure they cook evenly on both sides.
Remove from the oven and allow to cool. Once cooled, remove the stem, seeds, and skin. The skin should come off easily by scraping with a knife. Add the poblanos to the food processor or blender and blend until smooth.
Add the massa, blended poblano, and salt to a large mixing bowl. Slowly stir in the water, adding a little at a time, until the mixture is the texture of play dough.
Roll the dough into balls a little larger than a golf ball. Place the balls one at a time between two pieces of parchment or wax paper and press the ball in to a flat disc using a tortilla press or a rolling pin.
Place the skillet over high heat and cook the tortillas on each side until they start to brown.
