5-minute tomato soup

This is my favorite soup, and really quick and easy to make. My children are very fond of it, although I have still not been able to get my husband to eat it :) It literally takes 5 minutes to make.

Ingredients:
2 tomatoes
2 potatoes, peeled
1 onion, peeled
Seasonings to taste. I use salt, pepper, a dash of butter and Italian seasoning.

Method:
Cut the vegetables into four pieces each and microwave on high for 4 minutes. Puree in a food processor. Add the butter and season to taste. Serve.
