This recipe comes straight from my Mother-in-law's Central Pennsylvania recipe file. Folks living in that area frequently refer to ground beef as "Hamburg". I don't know why they do that, but my sister and I have always been tempted to say, "The word is hamburGER - Hamburg is a city in Germany!!!!" And although correct, it wouldn't be very nice so we keep our lips sealed.
At any rate, this is a classic recipe that's easy to throw together on a busy weeknight, especially if you have cooked ground beef or turkey in the freezer. I brown 5-10 pounds at a time, in small batches. For every pound of ground beef or turkey, I start off by sauteing 1 chopped onion and 2 cloves of minced garlic in a bit of olive oil; add the ground meat and kosher salt and pepper to taste. I drain, cool, and divide into 1 pound portions in freezer safe containers - great for quick meals like these sloppy joes, meat sauce, lasagna, soup, nachos, tacos, etc.
