Mashed plantains make for a tasty Cuban-inspired side dish.

2 fully ripe plantains, peeled and halved lengthwise

1/2 teaspoon coarse salt

Pinch of cayenne pepper, or more to taste

1 tablespoon olive oil

Juice of 1/2 lime

Preheat oven to 375 degrees. Sprinkle plantains with salt and cayenne; drizzle with oil to coat. Arrange, cut sides down, on a rimmed baking sheet. Roast until cut sides of plantains begin to caramelize, about 20 minutes. Turn plantains; roast 10 minutes more.
Mash hot plantains on baking sheet with a potato masher until somewhat smooth (some large chunks should remain). Transfer to a serving bowl, and drizzle with lime juice.
