Roast or grill bell pepper. Peel, seed, julienne and reserve for garnish. Cut lemon wedges and reserve as well. Chop tomatoes, mushrooms and the other vegetables we found at the market. Saute in the olive oil and allow to cook until liquid evaporates. Cut the chorizo into 1-inch rings and saute for 5 minutes (separately). Add chorizo to the vegetables in your paella pan. Add rice, saffron, almonds, herbs, salt and pepper. Top with stock. Stir well and bring to a boil. Cover and allow to simmer 12 to 15 minutes. In the meantime, clean your seafood. Then at 15 minutes, add seafood and cover. Allow to cook 6 to 8 minutes longer. Serve immediately, garnishing with the bell pepper strips and lemon wedges.
