Preheat oven to 375 F. Place sliced baguette on a large rimmed baking sheet. Drizzle with 2 tablespoons olive oil, then sprinkle with 1 teaspoon salt. Cook until crispy, but not browned, about 7 minutes. Remove and set aside.

Bring a medium pot of water to a boil, then add 1 tablespoon salt. Add peas and cook for 3 minutes. Drain and place into an ice bath. Cool for a few minutes and drain.

In a medium skillet, heat 2 tablespoons olive oil over medium-high heat. Sauté drained peas with garlic until cooked through, about 3-4 minutes. The peas should still have a little firmness to them — you don’t want them mushy.

On a large platter, layer crostini with ricotta, peas, and a few small leaves of mint (if they’re too large, you can tear or slice them). Season each crostini with sea salt and freshly ground black pepper. Serve at room temperature.
