In the food processor, add the sliced bread, potato, onion, cilantro, green chili, garlic, and ginger. Put the lid on the food processor and blend.
Add 1-2 tbsp of olive oil to the food processor to achieve a smooth consistency. Continue to blend for another 5-7 minutes.
Once everything has been combined, add the mixture from the food processor to the lean ground beef. Knead well so everything is combined. At this point add the garam masala and salt and mix.
Once salt and garam masala have been added to the meat mixture cover the bowl with a plastic wrap and let it sit in the fridge for a few hours.
Once you are ready to cook the kebabs, line a tray with parchment paper. Roll the kebabs into oval patties.
Bake in the oven for 25 min at 400 F and broil for 5-7 minutes at 450 F. Alternatively, broil at 450 F for 10 min each side two times until kebabs are cooked and have a dark golden brown crust. Enjoy on its own or in a pita or lettuce wrap!
