Ingredients
2/3 cup extra-virgin olive oil
2 1/2 Tbsp sherry vinegar
1 Tbsp dried herbes de Provence or Italian herb blend
1 tsp kosher salt
1/2 tsp freshly ground black pepper
Pinch red pepper flakes (optional)
3 large ripe beefsteak tomatoes, cored and cut into 3/4-inch chunks
1 medium red onion, halved and thinly sliced
1 large English cucumber, peeled, quartered lengthwise, and diced into 1/2-inch chunks
Fresh herbs for garnish (parsley, basil, chives, or chervil, optional)
Instructions
Prepare the Dressing In a large bowl, whisk together olive oil, vinegar, dried herbs, salt, black pepper, and red pepper flakes (if using).
Add the Vegetables Add the chopped cucumbers, tomatoes, and onions to the bowl. Toss gently to coat everything evenly in the dressing.
Marinate Let the salad sit at room temperature for 1 hour, stirring occasionally. Cover and refrigerate for at least 12 hours (or up to 24 hours), stirring every few hours to ensure the flavors meld.
Serve Remove from the fridge 30–60 minutes before serving to allow the flavors to bloom at room temperature. Toss again and garnish with fresh herbs if desired.
Storage Tips
This salad can be refrigerated for up to 4 days. Over time, the vegetables will soften, but any leftovers can be blended into a quick gazpacho or used as a flavorful dressing.
Serving Suggestions
Enjoy as-is, serve over greens, mix into pasta or rice, or top with crunchy pita chips for a twist on fattoush.
