Marinated Cucumber, Onion, and Tomato Salad (Fresh Summer Classic)
This Marinated Cucumber, Onion, and Tomato Salad is a light, refreshing, and flavorful side dish perfect for summer meals, barbecues, picnics, and family dinners. Crisp cucumbers, juicy tomatoes, and thinly sliced onions are tossed in a tangy, slightly sweet marinade that gets better the longer it sits.
Ingredients
2 large cucumbers, sliced
1 small red onion, thinly sliced

¼ cup water
¼ cup sugar

½ teaspoon black pepper
1 teaspoon dried oregano or Italian seasoning
