We cooked our kabobs on a griddle with a little bit of extra virgin olive oil (optional), but you can also grill them or cook them in a skillet (over medium-high heat) for 10 to 15 minutes each side or until golden brown. Remove from heat, add some salt and pepper to taste, some chopped chives for garnish (optional) and serve immediately.
Best when fresh, you can keep the kabobs in a sealed container in the fridge for 3 to 4 days uncooked or 2 to 3 days cooked.
