Shrimp Alfredo (Chicken Alfredo)

1 pound shrimp cleaned and de-veined (I cut mine into 3 pieces) - Can substitue chicken, cubed
½ cup purple onion, finely chopped
½ cup red pepper, finely chopped
10 garlic cloves, minced
1 tablespoon flour
2 cups heavy cream
1 cup parmesan cheese, grated
1 tablespoon red wine vinegar
¼ teaspoon dried mustard

In a saucepan, melt 4 tablespoons butter. Add purple onion, red pepper and garlic. Sautee until tender (about 3-5 minutes). Add shrimp and cook until pink. Add flour and cook 1 more minute. Slowly add cream and cook until begins to simmer. Add parmesan cheese, red wine vinegar and mustard. Heat until cheese is melted and sauce is thickened.
