I developed this recipe to lure my kids into eating spinach. It worked! Spinach in almost any form is one of their favorite veggies. Big "kids" enjoy these rich, filling potatoes as well, and I often make them for dinner parties. I haven't tried freezing them, but I imagine you could make a batch and stick them in the freezer to keep for another day.
Here's a tasty sounding recipe I found in a local newspaper. I haven't tried this one yet, but it's made with some of my favorite foods, so I imagine it'll be quite tasty. Per all reviewers I've changed the amount of chicken broth from the original 4 cups to 3 cups.
I got the original recipe from "Off the Hook". I reduced the amount of roux because I thought it came out too thick the first time I made it, but if you like thick sauce double the amounts of flour and butter for more roux. I also increased the amount of garlic :)
