Swiss, Ham,Cauliflower and Potato soup

Last Friday was a really dreary day with rain and damp and generally feeling like we need to be building an ark around here. For the month of October we have more rain than normal. This recipe did not have cauliflower in it but since we had half a head of one to use up we threw it in and no one would even know it was there as it blended in so well. So as the rain came down wife and I enjoyed this soup. By Susie on Zaar

2 med potatoes peeled and diced.
1/2 cup margarine (we use smart balance)
1/2 cup flour
2 green onions chopped or 1/2 yellow onion (we used yellow onion)
2-3 cups milk
4 slices swiss cheese
2 cups diced cooked ham
salt and pepper to taste
we also added a little garlic--- every thing can use some garlic
and we had some cooked bacon in the frig that we used as garnish.

Cook potatoes in saucepan in just enough water to cover, when tender drain and set aside and save liquid.
melt margarine, saute green onions or yellow onion until tender (we add garlic here). Remove onion and set aside.
Add flour to melted margin and stir until incorporated. Stir till the flour turns a golden brown (this is called a roux.)
Using a whisk stir in 2 cups of milk and 1 cup of saved potato liquid. Whisk until smooth and no lumps are seen.
Bring to a boil or until soup thickens.

Add diced ham, cooked onion(and garlic), swiss cheese (and cauliflower) Stir till cheese is melted.

Add salt and pepper to taste.

If soup is too thick add 3rd cup of milk if needed.

Garnish with bacon.
