This is the way my family celebrated Easter all my life, and I''m proud to say that I have continued this tradition. My mom took care of all the other holiday meals, but Easter belonged to my Dad. I remember when I first got my Lab Jolie, It was just before Easter and she got the bone as her Easter treat, and let me tell you, there is nothing sweeter than puppy breath from an olive oil smelling fur baby.
Preheat the oven to 325, wash and pat dry the leg of lamb. Mix the tomato paste and sauce together.
Make 8-10 slits, about 1/4-1/2 inch deep all over the meat and insert the peeled cloves of garlic. Using 1/2-3/4 cup of olive oil, massage it into the meat. Using half of the salt, pepper, Greek Seasoning and oregano, season the meat and massage them in. let stand 10 minutes.
Placing the lamb on a roasting rack pour half of the tomato mixture over the lamb, place the lemon pieces over the lamb and place in the oven and time it out at 20 minutes per pound.
With an hour left of cooking time spread the potatoes and carrots around the lamb season them with the remaing seasonings. and pour the rest of the tomato mixture over the lamb and veggies, turning to coat all over, and finish cooking the final hour.
