This recipe is great, but why oh why do you not provide serving/nutrition information for these recipes.

A very tasty and simple vegetarian recipe. The avocado with mustard and horseradish really work.

The Portobello was great... very yummy! But way too much horseradish and fresh lime juice in the spicy avocado sauce... not sure about the amount of spicy brown mustard because the horseradish and lime juice were so overwhelming. I couldn't taste any avocado. The spicy avocado sauce would be great with just a little less horseradish (coming from a person who loves horseradish) and lime juice. Definitely will make again!
