Greek Pasta Salad

1 pound bow tie pasta
8 oz. crumbled feta cheese (tomato/basil works best)
1 small can sliced black olives
2 cups shredded fresh spinach (never use frozen)
8 oz. Greek Salad dressing (fat-free works as well)
juice of one lemon

Cook pasta until al dente -- cool and add remaining ingredients. Stir and serve.  Excellent and, if using the fat free dressing, a healthy alternative to summer salads!
