Equipment

  • Wooden Spoon for mixing
  • Measuring Cup
  • Chefs Knife

Ingredients

Salad

  • 3 Vine Ripe Tomatoes cored, and quartered
  • 4 Plum Tomatoes cored, and quartered
  • 1 English Cucumber sliced thin
  • 1/2 Red Onion sliced
  • 2 tablespoons Fresh Italian Parsley finely chopped
  • 2 tablespoons Fresh Cilantro finely chopped
  • 1/2 teaspoon Brown Sugar
  • Salt and Freshly Cracked Black Pepper

Dressing

  • 1/2 cup Italian Extra Virgin Olive Oil
  • 1/4 cup Red Wine Vinegar
  • 3 Garlic Cloves minced
  • 1 teaspoon Brown Sugar
  • 1 teaspoon Dried Oregano
  • 1 teaspoon Salt

Instructions

Salad

  • Core the tomatoes, then cut into wedges and half the wedges. Slice the cucumber and red onion and place in a large bowl.
  • Add the parsley, cilantro, brown sugar, and salt and pepper to the bowl. Toss ingredients to coat.

Dressing

  • Whisk the dressing ingredients together and pour over the salad. Toss to coat and chill for 20 minutes before serving.

Notes

  • Choose high-quality olive oil for the dressing. Heat, light, and age all affect the polyphenol content of olive oil. You can rule out plenty of bottles in the store if they are not dark green or black in color. The green shade is a protectant of harmful light exposure. Extra virgin olive oil is the best you can purchase.
  • Don't slice your produce too small. This salad works best when you slice the produce into larger chunks.
  • Let the salad marinate overnight. I recommend making this salad the night before you plan on serving it so the vegetables can marinate in the dressing.
 

Storage Information:

 
  • Leftovers or if you make it ahead: place the salad in an air-tight container and store it in the fridge overnight. Making it ahead will allow the dressing to marinate the vegetables, which brings a stronger flavor. It will last in the fridge for about 5 to 7 days.
  • Before serving: if you make this ahead some or if it's been sitting for a little bit before you serve it some of the dressing will drip to the bottom of the bowl. Just toss and stir the ingredients again to evenly mix it all together.
