I use balsamic vinegar and olive oil in about equal parts with fresh ground pepper and salt as a dressing. I just pour some oil, then some balsamic vinegar and add salt and pepper to taste.
Salads are usually made with romaine lettuce, maybe a red or green leaf lettuce, rainbow bell pepper slices, yellow onion,green onion, radish, broccoli, cauliflower (if I have them), shaved carrot, tomato, some sort of meat ham, bacon, chicken, steak (whatever is in the fridge leftover) ad dressing and then cheese (again whatever is in the fridge usually cheddar but could be pepper jack, provolone, or another.
