In a large mixing bowl combine thawed peas (drained of any excess water), cut bacon, diced red onions, shredded cheese, and mayonnaise, and mix all pea salad ingredients together well.
Season salad with salt and pepper and mix again to incorporate seasonings.
Refrigerate pea salad 4 hours or overnight. Mix well before serving to prevent settling.
Chill for at least 4 hours and keep cold prior to serving.
