You can make your salad with or without lettuce and top it with tomatoes, cucumbers, red onion, feta and olives. Sometimes I see it with peppers too, but raw peppers are not my favourite.
I make the dressing in those little 1oz plastic cups and take it to work. So this recipe is enough for 1 salad. You could multiply the ingredients to make however many servings you want.
Greek Salad Dressing
1 serving (good for about 2 cups of salad)
2 tablespoons Kalamata olive liquid
1 teaspoon white vinegar
1 teaspoon olive oil (more if you like, but I prefer my dressing a bit sour)
1/2 teaspoon dried Greek oregano
1/4 teaspoon salt
1/4 teaspoon black pepper
Place all ingredients in the cup and put the lid on. Shake it. Shake it again before you drizzle it on your salad.
If you put this in the fridge, the oil will get clumpy. Either leave it out of the fridge until lunch time, or microwave the dressing for about 5 seconds before serving.
