Coat a pot with olive oil and heat up over medium-high heat. Add your onions, green peppers and garlic. Cook for about 5 minutes.
Once cooked, add the tomato sauce, dry white wine, white wine vinegar, red pepper flakes, salt, bay leaves, and parsley. Bring to a boil, reduce heat to medium-low and cover. Allow to simmer for 10 minutes.
After, add shrimp. Stir together with sauce, cover and allow to cook for five minutes or until the shrimp is no longer gray and turns pink. You will notice that the shrimp curls on itself and the two ends almost touch each other.
Once the shrimp is cooked, serve over white rice. Garnish with parsley and serve. Enjoy!!
