This is maybe my favorite summer salad, especially with cucumbers and tomatoes from the garden. You can use any type of onion, but red is the mildest and most likely for my kids to eat.
1 cup water
1/2 cup distilled White vinegar
1/4 cup veg. oil
1/4 cup sugar
2 tsp salt
1 tbsp coarsely ground pepper
3 cucumbers peeled and sliced
3 tomatoes cut into wedges
1 onion sliced and separated into rings
• Whisk water, vinegar, oil, sugar, salt, and pepper together in a large bowl until smooth; add cucumbers, tomatoes, and onion and stir to coat.
• Cover bowl with plastic wrap; refrigerate at least 2 hours.
