Preheat oven to 400 degrees F. Place butternut squash cubes on a baking sheet and toss with 1 tablespoon coconut oil to coat. Roast for 30 minutes or until tender.
Saute the onion until softened. Add the cauliflower, garlic, and ginger, and continue to sauté until cauliflower has begun to soften, being careful not to let the garlic burn.
