Jason's Deli Three Bean Salad - Inspired Recipe

Today at church, we celebrated Palm Sunday with a fried fish feast.  (Yep. In the Orthodox Church of America calendar, our Paschal/Easter services change each year; this year we are one week behind the Western calendar.)

I brought a three bean salad inspired by Jason's Deli.  It's completely Lenten (for oil days), and I wanted to type this up before I forget what I did.  :)

1 can dark red kidney beans, drained and rinsed
1 can garbanzo beans/chick peas, drained and rinsed
1 small bag (~1 lb) frozen lima beans
1 red bell pepper, chopped to size of beans
1 yellow bell pepper, chopped to size of beans
1 stalk celery, chopped to size of beans
1 small red onion, chopped
1 cup cilantro, stems removed and roughly chopped
~1 cup Italian dressing homemade or store bought

Italian Dressing:
1/2 - 2/3 cup olive oil
1/4 - 1/3 cup red wine vinegar
1 1/2 - 2 tsp salt
1 generous pinch each dried basil, dried oregano, dried Italian seasonings (ground slightly between fingers)
Pinch ground cayenne pepper
1 tsp each garlic powder, onion powder
1 tsp sugar

Mix all.  If you can, let it marinate overnight, stirring/shaking occasionally.
