Here is something I make, and you can add peppers

Shoepeg Salad

1 can white shoepeg corn
1 can early small peas (LeSeur is what I use)
1 can french style green beans
1 small onion, chopped finely
1 jar pimentoes
1 cup cider vinegar
1 cup oil
3/4 cup sugar
1 tsp salt
1/2 tsp pepper

In a saucepan, combine the oil, vinegar, sugar, salt and pepper. Add chopped onion. Bring to a boil, then simmer 5 minutes. Let cool. Drain all vegetables and mix them together in a bowl. Add dressing. Stir well, and refrigerate several hours until serving. Keeps a couple of weeks in the frig, supposedly, but mine never lasts that long! Good Luck!
