Paleo Gyros

0 Preheat oven to 325° and line a loaf pan with parchment paper. Set aside.
1 Quarter and peel the onion and place it in the food processor with the garlic. Pulse until chopped into small pieces.
2 Add the lamb, beef, cumin, thyme, oregano, rosemary, pepper, and salt.
3 Process until the mixture is evenly mixed and smooth. You may need to stop and scrap it down between pulses. The mixture will be very pasty looking and feeling.
4 Press mixture into the loaf pan, pressing it in tightly and evenly.
5 Bake for 55-60 minutes.
6 Pour off excess fat that cooks off. I always pour that into a bowl, let it cool, and throw it away.
7 Let cool on the counter and if possible, place a weight on it while cooling. I like to place another loaf pan on top and place a bag of beans or rice in there. This creates a dense loaf which is ideal for cutting.
8 Let cool in the fridge over night.
9 Slice into strips and pan fry in lard or coconut oil. Serve with onion, tomato and Tzatziki sauce.
