Instructions

Step 1: Prepare the Vegetables

Wash all vegetables thoroughly.

Slice the cucumbers into thin rounds or half-moons.
Thinly slice the red onion for a milder flavor.
Halve the cherry tomatoes or slice regular tomatoes into wedges.

In a separate bowl or measuring cup, whisk together:

• Vinegar
• Olive oil
• Sugar or honey
• Salt
• Black pepper
• Oregano
• Garlic powder
• Red pepper flakes (if using)

Whisk until the sugar is fully dissolved and the dressing is well combined.

Step 3: Marinate the Salad

Pour the marinade over the cucumbers, onions, and tomatoes.

Gently toss until all the vegetables are evenly coated.

Cover the bowl with plastic wrap or transfer to an airtight container.
