Preheat the oven to 350F and a large ovenproof skillet to medium-high heat with a drizzle of olive oil.
Add the chorizo to the skillet and brown for 7 minutes or so, breaking it up with a spoon as it cooks.
When the chorizo is cooked and browned, add the onion to the skillet. Stir the onions into the chorizo for 3 minutes.
Add the garlic slices and cook for one minute.
Add the tomatoes and saffron threads to the skillet with a sprinkle of salt. Stir to combine and taste; add more salt to your preference until the sauce is very flavorful.
Make little wells in the sauce and carefully crack the eggs into the sauce – try to keep each egg together and don’t stir the sauce after this point.
Place the skillet in the oven and bake for 10 minutes or just until the eggs are set and the yolks are still soft.
Sprinkle the capers over the dish. Let the sauce cool for about 5 minutes in the skillet, then serve with bread and crushed red pepper flakes. Enjoy!
