"Couldn't stop taste testing these, so we got less than the recommended number of servings. Will be freezing the leftover "dip" for future use in other dishes. Really delicious and easy to make. Be sure to use a hearty bread to soak up all the good flavors."

"My family loves these! I only use half a packet of soup mix to cut the sodium, but they are great without it. We like to eat these on Hoagie Buns from the Bakery."

"A family favorite! Have been making for years. I put less soy sauce in, 1/3 cup. I butter and toast bread under broiler, add meat and cheese, then put back in oven to melt cheese. They are just as good the next day for lunch."

"This has been a family favorite for years! I like to toast buttered French rolls under the broiler before putting the cheese and meat on the bread. Then I return them to the oven to melt the cheese. I also use less soy sauce; 1/3 cup is plenty. YUMMY!"

"This was good, but I found it didn't have all the robust flavor I was looking for. It could be because I used a pork roast instead. It was good, but not brag worthy."

"This was super tasty! Although I put two packets of onion soup mix in instead of one, I would suggest doing that if you like it a little more flavorful! But excellent, quick and easy meal! I have 4 young boys so I am always in need of something quick and easy!"

"Whole family, teenagers down to toddlers, loved it. My 3 year old kept thanking me for the "yummy hot dip" and would ask for more to drink after she'd dipped her sandwich. I used provolone on ours instead of swiss. Also, I had my butcher slice the roast very thin then froze it. When ready to use just let it thaw the night before and pour over the top of the onions. This cuts the prep time to about 5 min. for sauteeing the onions. Delicious."
