Preheat the oven to 400°F. Lightly oil a large sheet pan.

Toast the bread until just brown, then transfer it to a bowl and cover with water. Allow it to soak for about 5 minutes, or until very tender. Discard the water and squeeze the bread very dry. Crumble into a large, dry mixing bowl.

In a large skillet, heat the olive oil over medium heat. Add the spinach and cook briefly until just wilted. Remove from heat and let cool briefly.

Into the mixing bowl with the bread, add the ground turkey, onions, garlic, crumbled feta, egg, parsley, and mint. Add the wilted spinach and season with a big pinch of salt and pepper. Mix well to combine.

Form the mixture into balls (golf ball size) and arrange them on the prepared sheet pan. Bake in the heated oven for about 30 minutes, or until fully cooked through.

Transfer to the top rack and turn the broiler on for just a couple of minutes or until the tops are browned. Keep a close eye to ensure they don’t burn. Enjoy!
