Grab a large pot and fill it half-way with water. Set temp to high. Meanwhile, cut and peel the potatoes into medium sized chunks, season them with salt and pepper and toss them into the boiling water.
When the potatoes are almost done, toss in the 1 1/2 cup of broccoli, garlic powder, cheese and flour or corn starch. Season with salt and pepper. Stir and let cook for 10 minutes, more or less, on medium-low.
