In the interests of moving that post down a little, I'll post what I made for dinner yesterday. As an Irish girl it is a fall/winter staple, the potato soup.
First I take about 2 tbsp of butter and melt it in my pot, I add to that about 1/2 a large onion and about 1/2 cup chopped scallions. I put this on medium heat for about 30 minutes so its not frying the onions but just simmering. After about a half hour I add 5-6 peeled and chopped potatoes ( I chop them up very small) and about 5-6 cups of liquid (can be milk, chicken broth or water or any mixture there-of). Yesterday I added about 3 cups of 2% milk and about 3 cups of water. You let this come to a boil them simmer for about 30 minutes. I then take my immersion blender and blend it all up. Once this is done I just salt and pepper it up.
To serve, I grate up some cheddar cheese and put it on top of each bowl. Would be wonderful with bacon pieces on top as well.
This is a wonderful, cheap fall meal. The pot I made last night will probably last for 3-4 meals for two and the total cost was $2.78 (and thats with organic milk). So that is .35 cents per serving, not too shabby. Would be even cheaper if you just used water.
