Broccoli Chowder

1 10 oz package frozen chopped broccoli
1 medium onion, chopped (I use 1/2 of a red onion and cut it in big chunks so I can remove the onion pieces)
1 can Cream of Chicken soup
2 Tbsp. flour
1 1/3 c. milk
1 c. chddar cheese
1/8 tsp ground red pepper

Bring 1/2 c. water to boil. Add broccoli and onion. Cover and simmer 5 minutes. Do not drain. Stir in soup, flour, milk, cheese and pepper. Cook on low until soup is thoroughly heated.
