    YUM!! I don't like to buy onion soup mix because of the MSG, so I used dried minced onions, worcestershire sauce, 1 egg, salt, and pepper. This was super easy! Thank you so much for posting!

    I love the simpleness of this recipe. I served 85 people myself at a 4th of July party and spent less than an hour cooking. Use a pizza slicer to cut up the meat into little squares and add bread crumbs if you want the patties to be a little "fluffy". I used hawaiian sweet onions which turns slightly pink during cooking. It adds a nice colorful touch

    Delish! And SO easy :)


Just a regular person leading a very interesting life so far. I'm an administrative assistant...meaning I drive a mouse all day. I work like a dog and eat like a pig. <br> <br>My favorite cookbook is STILL the Old Settlement Cookbook (blue cover) that was given to me by my now dead, ex-FIL at my bridal shower. They tell you how to boil water and how to clean your house. I can do both! LOL! <br> <br>Favorite restaurant? Has to be DeMarini's pizza in Milwaukee, Wisconsin. <br> <br>In my spare time, I like to watch television, swim, eat, cook, and hang out with my DH. I have 2 grown bio daughters (LAUNCHED!), and am a evil stepmother to DH's 3 girls (thats a whole nother post!)
