Cut vegetables into 1.5 inch pieces and set aside.
Cut meat into 1.5 inch cubes(remove any fat and tendons) and place in container with tight fitting lid.
Squeeze lemon over meat. I use 2 if the lemons are smaller.
Crush dried oregano in the palm of your hand to release flavor and sprinkle over meat.
sprinkle salt and pepper over meat. I do about a teaspoon of each.
Crush garlic clove over meat.
Drizzle 1/2 cup olive oil over meat. Cover with lid and shake until well coated.
Set in refrigerator for 30 min up to two hours. *Remember the acid in lemon juice will start to cook the meat so don't leave it too long.
after about 30 minutes or so remove meat from the fridge and skewer meat onto shish-ka-bob sticks alternating with the vegetables.
Sear ka-bobs first and then cook over med/high heat on your grill or broil in the oven until the pork is thouroughly cooked - about 15 to 18 minutes. Make sure you watch it closely - I'm going by my grills cooking temperature and time...
I like to serve it with beef bullion flavored rice and a salad or spinich salad.
