Squashes can be cooked in various ways, such as roasting, sautéing, steaming, boiling, and baking. For roasting, cut the squash into small cubes, toss with oil, and roast in the oven for 20-30 minutes. For sautéing, slice the squash into thin rounds, add some oil to a pan, and cook until tender. For steaming, cut the squash into small pieces, place in a steaming basket, and steam for 10-15 minutes. For boiling, cut squash into small cubes, boil in water for 10-12 minutes, drain and serve. For baking, halve the squash and remove the seeds, season with oil, salt and pepper, then bake in the oven until tender.
