Quick Corn Chowder

I found this recipe on the vegetarian blog that I've used a lot lately http://www.v-gourmet.com/.  It was good, homey, and best of all, FAST!  The down-side (or up-side depending on your tastes) of this recipe is that it calls for a good amount of butter and cream.  I think it easily could be made with olive oil instead of butter and more veggie broth substituted for some of the cream.  We had it as a quick Saturday night meal with toast.  Danny of course wanted to add Tabasco sauce, and you may, if you wish... 

1 onion, diced
1-2 potatoes diced
2 Tab. butter
2 c. corn (fresh or frozen)
1 c. cream
1 c. vegetable broth
pepper and salt to taste

Saute onion and potatoes in butter until soft (about 5 min.).  Add cream, broth and pepper.  Cook about 10 minutes or until everything's soft.  Mash some of the potatoes if you like a thicker soup.  Add the corn and cook a few minutes if fresh, or about 5 minutes if frozen.  Season with salt.
