Cut chorizo into slices. Finely dice the onion and pepper.
Place a pot over medium heat. Add a drizzle of olive oil and brown the chorizo. Add garlic, onions, peppers, and sofrito. Sauté a few minutes until fragrant.
Add seasonings, chicken bouillon, tomato sauce, and roasted red peppers, if using.
Add the rice and the water. Stir everything until well combined. Taste the liquid for seasoning and adjust to your liking, if necessary.
Allow this to boil for a few minutes until some of the liquid is absorbed. Add a few sprigs of fresh cilantro on top. Cover the pot and reduce the heat to low.
Allow the rice to cook for 25 minutes, covered.
Uncover the caldero and remove the cilantro springs. All of the liquid should have been absorbed by the rice. If there is still some liquid left, cover and continue cooking 5 minutes more.
Carefully fluff the rice by lifting and flipping over spoonfuls of rice with a large kitchen spoon. The grains of rice should be fluffy and fully cooked.
Serve with tostones and salad. Enjoy! ¡Buen provecho!
