Cut squash into cubes and steam in a steamer with a tight fitting lid until al dente, about 5-6 minutes.
Heat 1 TBS broth in a medium size skillet. Healthy Saute onion in broth for 3 minutes over medium heat stirring frequently. Add garlic and spices and mix well. After about 1 minute add rest of broth and begin to simmer gently.
When squash is al dente, almost done, but still firm on the inside, add to simmering sauce and cook together for another 3-4 minutes. Season with salt and pepper and sprinkle with cilantro.
