Roasting: Preheat your oven to 400°F (200°C). Spread the frozen squash cubes on a baking sheet, drizzle with a little olive oil, and season with your fave spices. Roast for 25-30 minutes, giving them a good toss halfway through. Steaming: Add the frozen cubes to a steamer basket over boiling water. Cover and steam for about 10-15 minutes, or until they're fork-tender. Microwaving: Place the frozen squash in a microwave-safe bowl, add a splash of water, and cover. Microwave on high for about 5-7 minutes, stirring halfway through. Sautéing: Heat some oil in a skillet over medium heat. Add the frozen squash and cook for about 10 minutes, stirring occasionally. Feel free to add herbs and spices to amp up the flavor. Remember, frozen squash is already partially cooked, so it'll be ready to eat in no time!
