Start by heating 2 tablespoons of olive oil in a large paella pan.
Add onion and minced garlic cloves, and sauté until golden.
Next, add 1 cup of Arborio rice and stir it for a minute to coat it with the oil
Pour in chicken broth, saffron threads, paprika, and a pinch of salt. Bring it to a boil, then reduce the heat to low and let it simmer for 10 minutes.
Meanwhile, heat 1 tablespoon of olive oil in a separate skillet and cook 1 pound of chicken breast, 1 pound of shrimp, and 1 pound of mussels until cooked through.
Add the cooked meats and seafood to the paella pan, along with 1 cup of frozen peas and 1 roasted red pepper, sliced. Note: Arrange these ingredients on top of the rice. Cover the pan and let it cook for another 10 minutes, or until the rice is tender and the liquid is absorbed.
Once done, remove from heat, garnish with fresh parsley, and serve hot.
