Ingredients for Cucumber Salad With Onion

You can find most of these ingredients in a local grocery store. You may already have these ingredients in your kitchen, too.

Cucumbers: We use English cucumbers here because they are crisp and the perfect base for the cucumber salad. Persian cucumbers will also be will fine for this easy salad recipe.
Red onions: Freshly sliced red onion is robust and balances out the neutral flavors of the cucumbers. The onion absorbs the savory Italian dressing and really highlights the recipe.

Italian Dressing

Extra virgin olive oil: We recommend using extra virgin olive oil for the best aromatic flavors. Olive oil is rich with diverse flavors and allows this salad to stand out even more.
White wine vinegar: Tangy white wine vinegar is used for the salad dressing and gives the cucumbers and onions slightly acidic flavors that are balanced with the rest of the ingredients.
Honey: Sweet honey provides a subtle sweetness to the Italian dressing and rounds out the tangy flavors.
Oregano: Dried oregano is a fragrant herb that provides plenty of flavor to the dressing. Dried oregano can be found in most spice aisles in grocery stores.
Garlic: Fresh garlic provides an extra layer of flavor to the dressing and makes it extra savory.
Salt and pepper: Kosher sea salt and pepper are used to season the dressing until perfect. Use as little or much as you would like.
