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

What each ingredient does

Black beans: Add protein-rich body and a creamy texture that holds the filling together.
Zucchini squash: Adds moisture and tender bulk to the filling as it cooks down.
Cooked rice: Adds bulk and soaks up juices from the vegetables and tomatoes.
Diced tomatoes: Provide liquid and acidity that moisten and season the skillet mixture.
Onion: Builds a sweet, savory base as it softens in the hot oil.

The step that matters

Cook the onion until tender before adding the zucchini. Onion needs enough time over medium-high heat to soften and release its sweetness. Adding the zucchini too early can leave the onion raw and the vegetables unevenly cooked.
