I like to wash the outside of the squash and dry with a towel. Then poke the squash about 2 inches apart with a pairing knife.
Place on a microwave safe plate and place in the microwave. Cook for 5 minutes on high. Turn the squash, cook for another 5 minutes. Turn the squash one more time and cook another 3-5 minutes.
Test to see if the squash is done by gently pushing on the squash. It should give and feel soft to the touch.
Remove and let sit a few minutes so you can touch the squash. Cut in half, dig out the seeds. Dig out the squash and serve with your favorite topping.
