This avocado and smoked Gouda sandwich is one of my favorites. It's a perfect simple meal for a hot day! Ingredients:
sliced red onion
vegenaise or mayo
Lightly toast the sourdough bread under a broiler. Add the gouda, broil for a few more minutes until the cheese is slightly melted.
Top one side with tomatoes, vegenaise, salt & pepper.
Top the other half with spicy mustard, onion, avocado slices and lettuce.
