Below is a detailed, step-by-step guide to making delicious marinated cucumbers, onions, and tomatoes at home.

Ingredients

To prepare this refreshing salad, you will need:

2 large cucumbers
3 medium ripe tomatoes
1 medium red or white onion
½ cup white vinegar or apple cider vinegar
¼ cup water
2 tablespoons olive oil (optional for extra richness)
1–2 tablespoons sugar (adjust to taste)
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried parsley or fresh chopped parsley
½ teaspoon garlic powder (optional)
½ teaspoon dried oregano or basil (optional)

Step 1: Prepare the Vegetables

Start by washing all your vegetables thoroughly under cool running water.

Cucumbers: Slice them into thin rounds. If the skin is thick or waxed, you may peel them partially or completely depending on your preference.
Tomatoes: Cut them into wedges or bite-sized chunks. Choose ripe but firm tomatoes so they hold their shape in the marinade.
Onion: Peel and slice the onion into thin rings or half-moons. Thin slices allow the onion to absorb the marinade better.

Place all the sliced vegetables in a large mixing bowl.
