Gluten Free and Dairy Free Summer Salad Recipe: Cucumber Tomato Salad

Those of us who garden start to see the fruits of our labor this time of year (or in August for northerly climates), so I thought it would be a good idea to post my cucumber-tomato salad recipe:

Ingredients:
1 medium cucumber, peeled and cubed
1/4 cup red onion (diced)
3 medium roma tomatoes, cubed
1/4 cup red wine vinegar
2-3 Tbsp. sugar (to taste)
1/2 cup water
3 Tbsp. olive oil
salt and pepper to taste

Directions:
Mix all ingredients together in a bowl and leave them in the refrigerator for at least 3 hours, to marinade. Serve cold.
