When I lived in Spokane, WA, my little backyard garden produced more zucchini and beefsteak tomatoes that we could ever eat. I used to take grocery bags of both to work at the AF base for my troops, and all of it would disappear in a hurry. Glad to put them to good use.
I like them about 6-7" long and trim both ends and slice in half, lengthwise.
I then hollow out the middle with a spoon to be filled with........
meats, other vegetables, cheese, bread crunms etc. with olive oil drizzled on top
then placed in the oven with a alum. foiled cookie sheet which makes for a easy clean up job.
I like mine under the broiler to brown a little, before removing but just cooked is good also.
