Preheat grill to medium heat.
In a small bowl, mix together the olive oil, garlic, salt and pepper.
Place the green beans and tomatoes on a plate and brush with the olive oil mixture.
Place the green beans and tomatoes on the preheated grill and cook to desired tenderness, turning occasionally.
Remove from the grill and place on a serving plate. Dot with desired amount of jalapeno feta (very tasty, but can be spicy). Serve and enjoy!
