Marinated Pasta Salad - cooking recipe

Ingredients

8 oz. twist macaroni, cooked, drained and rinsed (I use the twist trio for color)
1 c. vinegar
3/4 c. sugar
1 Tbsp. mustard
1 tsp. pepper
1 1/2 tsp. garlic powder
1 Tbsp. parsley flakes
1 small jar chopped pimento
1 medium diced cucumber
1 small can sliced mushrooms
1 small jar drained and rinsed stuffed olives

Preparation

Marinate in refrigerator overnight before serving.
I stir several times during first few hours to make sure seasonings get into pasta.
