This dish is does not shy away from fat in the best way possible. From the lamb to the olive oil to the yogurt used as a sauce at the end, this is a one-skillet meal that feels worthy of a weekend spread. Since these meatballs aren’t made with binders like eggs or bread, they’re truly best made with a fatty meat like lamb. If you decide to use pork or beef instead, make sure it’s a mixture with a higher fat content or the meatballs could turn out dry. Since eggplant can really soak up oil when pan-frying, feel free to add more to the skillet as the slices cook.
