I literally threw this one together on the fly. My son gave me a head of cauliflower and a large bunch of broccoli that he didn't want. He knew they would go bad if he didn't use them or lose them. So I took them since I love both vegetables. Especially with a cheese sauce. I discovered I didn't have much cheese on hand--a bit of this and a bit of that. So I used what I had and--voila! Delicious!
Wash the broccoli and cauliflower and cut into florets. Peel the woody parts off broccoli stems. May also use stems if you cut them into small pieces.
Place the vegetables in a large pot of boiling, salted water over medium-high heat. Bring to second boil, reduce heat to low, cover and simmer about 15 minutes, or until vegetables are semi-tender. Drain.
In the same pot, add remaining ingredients to vegetables, chopping into smaller pieces as you go. Mix well, cover and allow to simmer on low heat until the dish reaches desired consistency, about 15 more minutes. Stir frequently to prevent burning.
This can be served as a side dish. It is very simple, nothing fancy. If you want fancy, look elsewhere! And if 1 teaspoon salt is too much for you, reduce it to suit your tastes. I happen to like a lot of salt.
