I made this today. It's really good - I usually make a pot of it about twice a month because everyone loves it so much and it's easy.

Dice and saute half a large onion in a big pot or Dutch oven. Use some butter and olive oil. Cube from four to eight chicken breasts and add to the onion. Stir in salt (a teaspoon?) and lots of freshly ground pepper. Meanwhile, cook one 16-oz package of frozen broccoli or the equivalent in fresh, then drain and set aside. When the chicken looks cooked, stir in one 8-oz block of cream cheese. When that has melted, stir in 1/2 cup whipping cream (optional) and one can of condensed cream of mushroom soup. You can add one soup can of water for a gravy-like sauce, or up to three cans if you want to call it soup. Mix in the cooked broccoli, heat and serve.
As you can see, this is a pretty flexible recipe so I can't give you an exact carb count, but a normal serving is a complete meal and will be less than 8 carbs if you subtract the fibre.
