Cut the squash in half lengthwise. Using a spoon scrape out the seeds and discard. Then cut into small pieces.
Heat a pot over medium heat. Once hot, add the oil, onions, and pepper. Saute until they start to soften and brown. Stir in the garlic and squash, saute until the garlic starts to brown. Stir in the turmeric, cumin, and flour and cook for 1 minute.
Then stir in the broth, cover with a lid, and simmer until the squash softens, about 15 minutes. Season with salt and pepper to taste.
Stir in the mint and sage right before serving. Serve with bread.
