Mixed Green Salad with Artichoke, Cucumber, Feta, and Apple

What do you get when you take a seemingly boring salad and add a few healthy goodies? A very pleasing dish that can be eaten by itself, as a side, or brought for a party/get-together. For those of you watching your fat intake, this salad is a great dish, loaded with veggies and easy on the waistline. Notice that I have not said "balsamic vinaigrette," as I often prefer the ease and ability to control the amount oil and vinegar by themselves. If you are a major vinaigrette fan, however, simply toss in a teaspoon of dijon mustard to your emulsification of oil and vinegar.

Mixed Green Salad with Artichoke, Cucumber, Feta, and Apple:

2 handfuls of mixed greens (I like to buy them in a box at the grocery store)
1 jar of artichoke hearts, drained
1 cucumber, diced
3 stalks celery, thinly chopped
1 apple, diced with skin on
1/4 cup feta cheese
3 Tbs. olive oil
3 Tbs. (or to taste) good quality balsamic vinegar

Salt and pepper to taste
