Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggplant: Becomes tender and adds bulk and moisture to the skillet mixture.
Cream of mushroom soup: Provides creamy moisture that binds the rice, tuna and vegetables together.
Cheddar cheese: Melts into the top layer, adding richness, savory flavor and a gooey texture.
Cooked rice: Adds starchy bulk that soaks up the soup and holds the skillet together.
Tuna: Supplies the main protein and savory flavor of the dish.

The step that matters

Cook the eggplant until tender crisp. Eggplant soaks up fat quickly and can turn mushy or greasy if overcooked, while undercooking leaves it spongy. Stopping at tender crisp keeps its texture intact through the later heating.
