There's still a few really good grilling days left and this Grilled Eggplant is a good one to try. It's a real quick and easy one.
North African Style Grilled Eggplant (Adapted from Real Simple*)
3T olive oil
2 T honey
1T ground cumin
1 medium eggplant, cut into 1"thick rounds
Mix oil, honey, and cumin together. Make slight cuts on both faces (do not cut through) of the eggplant. Brush with honey/oil mixture. Place on grill over indirect heat. Close lid. Cook until tender and slightly browned. Turn and cook until browned - total about 20 minutes.
Easy - peasy. It's hardly even a recipe.
