If you can’t find green olives stuff with garlic, you can use 1 cup of large green olives and toss them with 2 cloves of minced garlic. Toss the lemon, red onion, kalamata olives, and thyme with the olive oil, salt & pepper. Add to the sheet pan and then toss the green olives with the garlic in the same bowl, add to sheet pan. This keeps the garlic from coating the lemon.
