Preheat oven to 350° F.
Gently toss beans, carrots, cauliflower, broccoli and seasoned rice together, along with optional ingredients, if using.
Dip tortillas in warmed green enchilada sauce, put each tortilla on an oven-proof dinner plate and fill with above mixture. Roll up and place, seam-side down, in center of plate. (of course, you can have more than one on the plate, if you're very hungry or the tortillas are small!)
Cover with more green enchilada sauce and top generously with cheese.
Place plate(s) in oven and bake until it's hot through and cheese is melted and bubbly.
Serve with flour tortillas.
May serve with picadillo, sour cream, cold crisp greens and warm, crunchy chips.
