I used these gorgeous beets for a salad, but you could serve them on their own as well.
2 medium sized beets
1-2 tsp olive oil
Wash and peel the beets. Slice into 1/4 to 1/3 inch slices. Brush both sides of each slice with olive oil. Grill for about 8 minutes on one side, then turn, and grill 6-8 minutes on the second side.
