This turned out really well! I used fresh broccoli, about a head, and added it about three or four minutes before the pasta was done. For the sauce, I toasted the flour in the pot over medium heat for about 4 or 5 minutes, stirring constantly before whisking in the milk. I didn't think it tasted to flour-y at all using this method. Also I used w.w. rotini instead of elbows and added about 4 ounces of chopped cooked chicken breast at the end. Yum! A hit with the fam and the serving size was generous.
