The Secret: Only the Best Produce
The single, uncompromising rule for making this salad unforgettable: Accept no mediocre produce! Make it in the height of summer, when tomatoes, plums, and cucumbers are at their peak—ripe, flavorful, and bursting with juice. If a listed ingredient doesn’t look stellar in the store or market, swap it for another vibrant fruit or vegetable. This salad is about celebrating what’s best and freshest each season.
No need to limit yourself to any particular variety or shape of tomato, plum, or cucumber. In fact, mixing several creates more visual and flavor interest. The only requirement is that every fruit and vegetable is bursting with flavor and freshness.
Key Ingredients in Summer Tomato Plum Salad
- Tomatoes (about 4 cups): Use small, medium, or a colorful mix—heirlooms, cherry, grape, or vine-ripened all work.
- Plums (about 1 pound): Any variety should be sweet, tart, and firm, so they hold their shape when sliced.
- Cucumbers (about 1 cup): Persian or English cucumbers are preferred for their thin skin and crunch, but any cucumber will do.
- Red Onion (about 3/4 cup): Brings mild sharpness and a pop of color.
- Fresh Herbs (1/2 cup): Basil, mint, cilantro, or a combination, torn or chopped just before serving.
- Vinaigrette: 2 tablespoons freshly squeezed lemon juice, 2 tablespoons extra-virgin olive oil, 1 teaspoon honey (or agave), and 1 teaspoon ground sumac.
- Seasonings: Kosher salt and freshly ground black pepper, to taste.
Helpful Ingredient Swaps and Variations
This salad is highly adaptable as long as the produce is excellent. Here are some favorite and creative swaps:
- Fruits: Try nectarines, peaches, or apricots instead of plums for a different sweet-tart profile.
- Melon: Honeydew stands out as a fun substitution for cucumber, offering a unique sweet-savory twist.
- Herbs: Swap cilantro in for mint or basil, or mix several for added complexity. Dill also pairs well.
- Onion: Shallots or sweet onions work if red onion is too pungent.
- Vinaigrette Variation: Lime juice instead of lemon, or a splash of white wine vinegar, will work in a pinch.
The end result should always be juicy, refreshing, and packed with seasonal flavor, so don’t be afraid to improvise based on what’s in peak condition at your market.

Frequently Asked Questions (FAQs)

You can prepare the dressing and chop the vegetables hours ahead. For best results, toss together no more than an hour before serving, and stir in herbs just before eating for peak vibrancy.

Pack the salad base and vinaigrette separately and toss together on site. Keep herbs in a separate bag and fold in right before serving for freshest flavor and color.
