Cube the chorizo and sautee it with a little olive oil. Then chop the onions and garlic and add them to the chorizo. Preheat the oven to 350.
Place in a baking dish. I love my pyrex because it doesn't burn the bottoms and it is so easy to clean. Place into your 350 degree oven and wait for 20-25 minutes.
Once they are golden brown and the peppers have softened you are ready for tapas that eat like a meal. I suggest pairing this dish with a red wine: Rioja from Spain, Pinot Noir because it goes with everything, or even a Malbec from Argentina. A nice light side salad of arugula with lemon vinagrette would be pretty tasty too.
