Summer is for vegetables

Even though my husband and I pretend to be adults, neither of us is too fond of vegetables. Sure, we'll eat salads happily, but most cooked veggies go to the wayside. But both of us die for this cool summer salad, we can eat it nonstop. The recipe has been in my family for ages, so I'm not real sure where it came from. Here it is, for the culinary and the curious.

TOMATO, CUCUMBER, & ONION SALAD

1 medium onion
2 medium tomatoes
1 small cucumber
1 cup sour cream (I use 200 gr. yogurt)
2 tsp. apple cider vinegar
1 tsp. sugar
1 tsp. salt

Slice onion into thin slices. Soak in water 10 minutes. Dice tomatoes, pare cucumbers. Cut into thin slices and in half. Add vinegar, salt, and sugar to sour cream. Mix in vegetables and set aside 1 hour in refrigerator. Serves 4. Recipe may be doubled for more servings.
