This was born one night when I was trying a new recipe, but didn't have all the right ingredients. It's bits and pieces of 2 recipes plus my own additions. Awesome with fresh mushrooms, but very good with canned as well. I used to always buy the Knorr Herb and Garlic Sauce packages to make this dish, but haven't been able to find them for the last couple of years. This is VERY close to the same flavour, if not an exact duplicate, so that's exciting for me! Depending on how saucy you like your pasta, this is enough for 2 main course servings and up to 6 side dish servings.
