💡 Tips for Success
Use Fresh, Ripe Produce
The better the tomatoes and cucumbers, the more flavorful the salad.
Slice the Onion Thinly
Thin slices mellow nicely in the dressing without overpowering the other vegetables.
Salt Just Before Serving

Chill Briefly
A short rest in the refrigerator allows the flavors to blend while maintaining the vegetables’ freshness.
