Peel and cut 1/2 small butternut squash into wedges; toss with olive oil and 1 teaspoon each crushed coriander seeds and kosher salt. Bake on a preheated baking sheet at 425 degrees F until tender, 25 to 30 minutes. Spread ricotta on 4 slices multigrain toast. Top with the squash. Drizzle with honey and sprinkle with pepitas, mint and salt.
