1. Set a paella pan over a grill on medium-high heat and pour 1/4 cup of olive oil. Season the chicken with 2 tablespoons of Essence and 2 teaspoons of salt. Once the oil is hot sear the chicken in the pan until well caramelized, about 4 minutes per side. Remove the chicken from the pan and set aside. Add the rest of the olive oil with the chorizo to the pan and sear, stirring occasionally, until well caramelized, about 7 minutes. Add the onions, red and green bell peppers to the pan and sweat until softened, about 5 minutes. Add the garlic and saffron to the pan and return the chicken to the pan as well. Pour the stock in the pan and bring to a boil. Reduce the heat to medium and cook the chicken for 10 minutes. Add the rice to the pan and carefully stir to incorporate. Continue to cook the rice for 15 minutes. Season the shrimp with the remaining Essence and 1/2 teaspoon of salt and add to the pan with the mussels tucking them under the rice. Continue to cook until the shrimp turn pink and the mussels begin to open, about 5 minutes. Add the peas, turn the heat to low and continue to cook the paella until a crust begins to form on the bottom of the pan, about 5 to 7 minutes more. Serve while hot.
