Heat a large skillet over medium high heat and add the CHORIZO. Cook until browned and broken up into small pieces, then remove with a slotted spoon & set aside.
To the pan, add the GARLIC, ONION, and RED BELL PEPPER, and cook for 2-3 minutes to soften.
Add the CHICKEN - cooking for about 3 minutes, or until lightly browned on the outside but not cooked through.
Add the RICE, and mix well to coat it with the oils from the pan.
Add the chorizo back to the pan, and stir in the CHICKEN BROTH, drained TOMATOES, and SAFFRON.
Bring the dish to a simmer, then lower the heat to a gentle simmer so the bottom doesn’t burn. No more stirring! Simmer for 10 minutes, uncovered.
Add the PEAS, scattering over the top. Add the SHRIMP, submerging down into the rice mixture a bit.
Cook for 8 more minutes or until the shrimp are opaque & cooked through, and most of the liquid has been absorbed by the rice (some liquid remaining is good!) Remove from the stove once the rice seems cooked but still firm.
While off the heat, scatter the CLAMS over top, cover the pan with a lid, and rest for 5 minutes while the remaining liquid is absorbed by the rice.
Garnish the dish with fresh chopped parsley and wedges of lemon to serve. Enjoy!
