      Had to use a cup of milk, and since we don't have valveeta in South Africa I just used gouda and mozzarella. Came out beautifully! For once a meal that looks like the pic.

      A winner! I turned it into more of a main dish by putting a layer of sliced mushrooms on the bottom and strips of pre-cooked bacon on the top. I also substituted shredded cheddar for the cheese and cream for the milk. It was a nice, rich dish that was easy to make and re-heated well, too!

      I made this dish 2/16/18. The only 2 changes were: I used 1 cup milk and 1 lb. cauliflower-broccoli blend thawed in my microwave. This dish is delicious and a real recipe keeper!

      Great dish. Very easy, making cheese sauce versus using a soup makes the difference. Dish is very light and tasty whether using Velveeta or cheddar cheese.

      This is an excellent side dish, although you could add sausage or chicken and make it a main dish. Easy to prepare. I used shredded cheddar cheese instead of velveeta and it worked fine. Delish!
