UPDATE 8/8/2011: I turned this dish into a main dish by adding pan-grilled chicken. I also added marinated artichoke hearts and adapted this dressing. It turned out super delicious.
lettuce or baby spinach
feta cheese, crumbled
marinated artichoke hearts
pickled banana peppers
red wine vinegar
salt and pepper
For dressing: whisk together red wine vinegar and olive oil (approx. equal parts of each, maybe slightly less vinegar) and salt and pepper.
Assemble salad and toss with dressing.
