One of my favorites is a sautee in OO with some red pepper flakes and feta.
Just halve length wise, slice 1/4' or so, into a hot pan with a bit OO, when about half way done I sprinkle a bit of feta and red pepper on top and cover until done. I like mine a bit under cooked.
Often mix in Zucc and onion.
Can also halve, hollow out the squash, and then fry some ground meat (beef/sausage/venison whatever) with some of the squash guts and then fill the halves. Add rice and tomato if you wish to the meat and squash. Any stuffed pepper recipe works well for the filling.
