Cut 5 (16inx12in) parchment paper sheets and set aside. Or buy precut ones.
In the bowl of your food processor add onion and garlic then puree.
Add ground beef with all other spices and yogurt without the olive oil and pulse until it is light in color and forms a paste.
Pour the meat mixture into a large bowl, drizzle oil over it, and mix with your hands. This step is done so that the meat mixture is more manageable.
Preheat oven to 400F.
Divide the mixture into 4 equal parts and oil (or use an oil spray) one sheet of parchment paper.
Place another sheet of parchment paper on your cutting board or working surface.
Wet your hands lightly with oil and spread ¼ of the meat mixture over the sheet pressing lightly.
Cover the meat mixture with the oiled parchment sheet (oily part facing the meat mixture) and spread the meat mixture with a rolling pin as thin as you can.
Remove the upper parchment paper and roll the meat mixture, keeping the bottom parchment paper on.
Place on a baking sheet and continue with the remaining meat mixture so now you have 4 meat rolls on your baking sheet.
If you are using place the vegetables in the tray and oil with some olive oil and sprinkle with salt and black pepper.
Bake in the oven for 25-30 minutes.
