This recipe creates flavorful Greek-style stuffed mushrooms. Large mushroom caps are filled with a mixture of chopped tomatoes, Kalamata olives, crumbled feta cheese, garlic, and fresh basil, then baked until tender and heated through. They make an excellent appetizer or side dish.
Select large, firm mushrooms for easier stuffing. Cremini or button mushrooms work well. Ensure tomatoes are well-seeded to avoid excess moisture in the filling, which can make the mushrooms watery. Kalamata olives offer a distinct briny flavor essential to the 'Greek' profile; use good quality ones. Crumble the feta cheese finely so it integrates nicely into the filling. Chop the garlic and basil very finely to distribute their flavors evenly.
