A refreshing and simple cucumber and tomato salad featuring thinly sliced red onions and fresh dill, tossed in a tangy red wine vinegar and Dijon mustard vinaigrette. Perfect as a light side dish or an easy summer salad that comes together in just 10 minutes.

Ingredients

Salad Ingredients

  • 3-4 ripe tomatoes (preferably heirloom tomatoes)
  • 3-4 Kirby cucumbers or 1 thin English cucumber
  • 1/3 red onion (sliced thinly)
  • 1 tbsp fresh dill (or herb of your choice)

Vinaigrette Dressing

  • 2 tbsp red wine vinegar
  • 3 tbsp good quality extra virgin olive oil (unrefined recommended)
  • ½ tsp Dijon mustard (or multigrain mustard)
  • Salt to taste

Instructions

  1. Prepare the Vinaigrette: In a small mason jar, combine the red wine vinegar, extra virgin olive oil, Dijon mustard, and salt. Put a lid on the jar and shake vigorously until the vinaigrette emulsifies into a smooth dressing.
  2. Slice the Vegetables: Using a mandolin or a sharp knife, thinly slice the cucumbers, tomatoes, and red onions to ensure even texture and ease of eating.
  3. Combine Ingredients: Place all the sliced vegetables in a salad bowl. Add fresh dill or your chosen herb on top for added flavor.
  4. Toss with Dressing: Start by adding 2 tablespoons of the vinaigrette to the salad and gently toss to coat all ingredients evenly, being careful not to tear the thin slices. Add more dressing if desired to taste.
  5. Serve: Serve the salad immediately for the freshest taste. Reserve any leftover vinaigrette for future use.

Notes

  • Using heirloom tomatoes adds a lovely sweetness and vibrant color.
  • Thin slicing is key to avoid overpowering the delicate textures.
  • The salad is best eaten fresh but can be refrigerated for up to a day with dressing held separately.
  • Feel free to substitute fresh dill with parsley, basil, or cilantro for a different herbaceous note.
  • The vinaigrette can be adjusted to your taste by varying the amount of mustard or vinegar.
