How about this one, from Annabel Karmel?
Vegetables with cheese sauce:
1 cup chopped cauilflower florets
1/2 cup chopped broccoli florets
1 medium carrot, peeled and sliced
1/4 cup frozen peas
Cheese Sauce
1 Tbsp unsalted butter
1 Tbsp flour
1 cup milk
1/3 cup grated cheddar cheese
Put all veggies except peas into steamer set over a pan of boiling water and cook for 4 minutes. Add peas and cook for 3 minutes. Make cheese sauce... melt butter in pan, stir in flour to make smooth paste and cook 1 min. Gradually stir in milk, bring to a boil and cook a few min over low heat until thickened and smooth. Stir in grated cheese until melted
Put veggies in blender, pour in sauce and puree, or chop veggies and mix with sauce (depending on consistancy stage). You can add cooked pasta into the blender as well.
