I first started by roasting grape tomatoes. This is best to be done the morning that you want to eat the salad or the day before. It's a slow process and they roast for a few hours on 200-250 degrees Fahrenheit for a good 2-3 hours. It seems like a long time but your cooking these low and slow. I make these often during tomato season. They are sooo good. Next up, make the homemade Greek Salad Dressing. This recipe makes a little less than 1 cup which is great for small batch salads and should be plenty of dressing between the 4 salads. You'll also want to cook your quinoa too. Then, once you've done all the prep work it's time to assemble the salad.
