cauliflower alfredo

I found this in a Cooking Light magazine, and it was a huge hit with the kids. M's eaten this for either lunch or dinner now for more than a week! The cooked cauliflower makes for a more luscious, healthier, but still creamy alfredo sauce.

cauliflower alfredo
makes 8 servings

1 lb uncooked fettucine (or spaghetti/linguine)
6 cups chopped broccoli
6 cups chopped cauliflower, divided
2 tbsp flour
2 cups chicken stock or broth
6 garlic cloves
1 1/3 cup milk
3 tbsp unsalted butter
2 tsp freshly ground pepper
2 tsp grated lemon rind
2 tsp lemon juice
1 tsp salt
4 oz Parmigiano Reggiano cheese (divided, about 1 cup)

Cook pasta according to package directions. Add broccoli and 2 cups cauliflower during the last two minutes of cooking, drain.

Place flour in a large saucepan. Gradually add stock, stirring constantly with a whisk until blended. Bring to a boil over medium heat; cook 2 minutes or until thick, stirring constantly. Add remaining 4 cups cauliflower and garlic. Bring to a boil, cook 15 mins or until very tender.

Place cauliflower mixture in a blender (or use an immersion blender). Return cauliflower mixture to pan. Add milk, butter, pepper, juice, salt and 2 oz cheese. Reduce the heat to low and add pasta mixture and lemon rind; toss well to coat noddles. Sprinkle with remaining cheese.
