Ditto on Erzaglenn on stuff it with cheese.
I remember my mom used to make stuffed zucchini.
First you cut lengthwise of zucchini
fill about one inch of water in pan (if you can find a big pan) smile
face half zucchini side down
cook until inside of zucchini is soft
Scrape out zucchini with ice cream scoop, put in bowl, mix with cooked hamburger, cooked onions, spaghetti sauce (rice or no rice optional) cheese and cook for about 20 mins?
then put more cheeese on top and broil til cheese melt.
Enjoy!
