JB's Chipotle Macaroni Shrimp Salad

My husband loves this salad, and I may have posted it a while ago, but I changed it a little.
Ingredients:

1/2 pound cooked macaroni
1/2 pound cooked,chopped shrimp
3/4 cup mayonaise
1/2 yellow pepper, chopped
1/4 red onion,minced or chopped finely
1 tsp salt
1 tsp pepper
1 Tbsp chipotle (chop one from the can, you can freeze the rest) Use some of the sauce from the can, too, if you like it a little more spicy
