This recipe excels for one of my most quick and easy recipes.
Rinse the salmon fillets and pat dry with paper towels. Liberally salt and lightly pepper the fillets.
Add the olive oil to a heavy metal skillet and heat over medium-high heat. Add the chopped green pepper and saute a minute or two.
Push the sauteed green bell pepper to the sides of the skillet and add the salmon fillets (skin side up). Fry for about 5 minutes on the first side. Watch for the sides turning white. Do not try to move the fillets while cooking.
Flip the fillets over, using a metal spatula to get in under the fillets. Continue cooking for a couple of minutes.
Reduce the heat to medium and add the sweet and sour sauce and pineapple. Cook for 1-2 minutes more until everything is heated. Serve immediately.
