Thanks for the tips Mrs. H! I've made the hamburger thing with acorn squash before, never thought about trying it with zucchini squash...the only difference is that I don't fry the burger first...I form the burger to the squash "bowl", put all the stuff in the raw burger, put it in the oven, cover it with a little water, then let it bake...flavors infuse into the squash...don't want to do this with real fatty or watery burger I wouldn't think.
I'm making some relish tomorrow night, then I'll shred what ever I don't use and freeze it for breads and the like...thinking I'll just cut some up and freeze it for use later in soups and casseroles too!
Hoping the rest of our garden starts coming along nicely -- I'm looking forward to getting some homemade salsa canned!!!
