From Simple and Delicious - boy I love this magazine! Submitted by T. Perrault. I love how she combined cauliflower, broccoli and zucchini within this recipe. Just a lovely combination. Feel free to use already prepared Alfredo sauce or your own recipe for Alfredo sauce. I made this once as a side dish and realized it makes a large amount, so then the next time I added some cooked chicken to make it a main meal. Serve with crusty bread and you are done!
