Recently I purchased Aldi's, LiveGFree, mac and cheese (from their Gluten Free line)---yes, mac and cheese in a box! You can follow the directions on the back of the box or you can do like me and just eye ball the water.
If you want to give Aldi's Gluten Free mac and cheese a homemade look, once it is finished cooking just spray an 8x8 pan with cooking spray and put the mac and cheese in there, place in a 400 degree preheated oven until the top is golden brown (10 to 15 minutes); it will be a little crunchy around the edges too---yummy goodness!
You can find this and more LiveGFree items in all Aldi's Stores. Plus you can go here at THIS LINK to read more about the Gluten Free products.
