1. Cut the cauliflower florets into large chunks and put them in a pan. Then add enough water to cover the florets and sprinkle in a tablespoon of salt.
2. Boil the cauliflower for five to seven minutes on high heat. Then, check for doneness by piercing the florets with a fork.
3. Drain the florets in a colander and dry with paper towels. Then, pour the butter into a pan and cook briefly over medium heat. Stir in the onion and garlic powder, and when it thoroughly mixes, turn off the heat.
4. Serve the cauliflower hot, with the butter and seasoning mix, poured on top.
