I have been making these for 40 years and eating them since I was a kid. My Momma used to put cabbage in hers. I like the zucchini squash and broccoli also. You can pretty much use any veg you want in these. Be sure to use butter or margarine for a sauce that is yummy. Otherwise it will be too dry. It may not look very pretty but it is delicious.
1Pre heat oven to 400 degree.
First I get a heavy duty aluminum foil and make 2 sheets where they cross each other in the middle. (to make it larger than a regular sheet). Place a good portion of hamburger, in a patty, approx. 7 to 9 inches in diameter and about 1/2 to 3/4 inch thick, on the foil. Salt & pepper to taste.
2Place sliced onions and potatoes next on top of the hamburger. Salt & pepper again. (some will slide off to the side) That is ok.
Then place the squash and broccoli (or what ever veggies you have) on top of that. Pyramid style. Again, it's ok if they slide to the side a bit.
3Salt & pepper to taste again. (we like salt & pepper) Add the butter or margarine on top of all of the veggies. I use about 2 - 3 Tbsp. on each serving depending on the amount of veggies added.
4I then fold it up around the whole thing. Try to keep it as triangular as possible. Add another piece of foil underneath of this and fold it up around the whole thing. This is to catch any liquid that might seep out. Seal it up on top.
5Bake at 400 degrees for approx. an hour. Check it at 45 minutes and see it the potatoes are soft. The meat should be done if it is not too thick of a patty. The juice is what is great with this meal it is the best tasting veggies ever. And you just dump it onto a plate and enjoy it. Throw the aluminum foil away. And not much left to clean up too.
