In a medium mixing bowl, pour in the rice and the chicken stock. Let these sit about 10 minutes.
Cut the bell peppers in half lengthwise. Use a small sharp knife, like a pairing knife, to remove the seed, the veins, and the seed cap at the top, but leave the stem intact.
Add the bell peppers and par-cook them for 3 minutes.
Meanwhile, in a medium skillet, heat 1 tablespoon of olive oil over medium heat. Add the onion and season them with salt. Cook until they are translucent, about 5 minutes. Remove them to a bowl.
Add the crumbled chorizo to the same pan and cook until firm, about 5 minutes as well.
In the mixing bowl with the rice and chicken stock, add ground chicken, chorizo, onions, Spanish olives, 1 tablespoon parsley, salt, and pepper, and thoroughly mix.
Garnish with fresh parsley.
