Drain the liquid off of the tomatoes. Pour into a saucepan with the vegetable broth, bring to a boil, reduce heat and simmer for about 30 mins. Pour the tomato mixture into a blender, add basil leaves, and puree. *CAUTION: puree in small batches. Don't try to puree it all at once, even if it looks like it all fits in the blender. The steam will force the top off of the blender and the boiling hot liquid will burn your tender little hands. Not that I'd know. I'm just saying.* Anyhow, puree until smooth and return to the saucepan. Stir in earth balance and soymilk, and add salt and pepper to taste. Heat for a few more minutes until margarine is melted. Pour into a bowl. Eat and feel cozy.
