Gyro made with fresh herbs

I have an oregano plant growing way beyond its bounds in the garden, and don't want to just throw away the excess. In trying to figure out what to do with it other than drying, I decided to make this classic dish using fresh oregano instead of dried. They're awesome with Tzatziki.

1 lb ground beef
1 lb ground lamb
⅔ cup fresh oregano
½ onion, fine mince
4 to 6 garlic cloves, pressed
1 tsp ground dried rosemary
1 tsp ground cumin
½ tsp ground pepper (or more)
1 Tbsp fresh Thyme
1 tsp salt

1. Preheat oven to 390°F.
2. Mix all the ingredient together. Mix it up real good.
3. Make meatballs about 2 oz each.
4. Bake for 20 minutes or until internal temperature reaches 160°F.
