Step 1- Chop Your Vegetables
Chop the cucumber, tomato, and onion, then place everything in a large serving bowl. Keep the pieces relatively bite-sized so every forkful gets a good mix of textures.
Step 2- Make the Dressing
In a small bowl, mix the rice vinegar, lemon zest, lemon juice, and lemon pepper. Whisk together until fully combined. The mixture should smell bright and citrusy before it even hits the vegetables.
Step 3- Combine and Taste
Add the dressing to the main serving bowl with the chopped vegetables. Toss well, then taste test and add salt if needed. Every batch of tomatoes and cucumbers is a little different, so trust your taste buds here.
Step 4- Garnish and Serve
Top with freshly chopped dill if you're using it, then serve right away. This salad tastes best fresh, though it holds up reasonably well for a few hours in the fridge too.
