In a pan over medium heat, sauté onion and garlic in olive oil for about 4 minutes.
Next, add in the lentils and ground beef. Saute and cook for 7 minutes. Once it’s browned and cooked all the way through, add in the tomato paste, spices, and oat flour. This mixture should be thick.
Then cut the pita just the top off and very gently open it up. Now, stuff it with the meaty filling (as much or as little as you want).
Once all pitas are stuffed and you’ve used up the meaty mixture, clean the pan out.
Then, reheat the pan back to medium/high heat and spray with oil. Sear the open side of the pita face down on the pan for about 2-3 minutes until brown.
Make the tahini yogurt sauce in a jar by adding all ingredients and mix well until combined. Be sure to finely chop the herbs. If you want a smoother texture, you can blend the sauce. Then, serve with the stuffed pitas and enjoy!
