Heat the vegetable oil in a large pot over medium-high heat.
Add the lamb or beef chunks and cook until browned on all sides.
Add the chopped onion, sliced carrots, and potato chunks to the pot.
Stir in the salt, ground black pepper, and ground cumin if using.
Add the unpeeled garlic cloves.
Pour in enough water to just cover the ingredients.
Bring to a boil, then reduce the heat to low, cover, and simmer for about 1-1.5 hours, or until the meat and vegetables are tender. Check occasionally and add more water if necessary.
Garnish with fresh herbs if desired.
Enjoy your meal!
