2 slices Bread
1/2 Avocado, pitted and thinly sliced
3 slices Tofutti 'American-Style Cheddar' (or other vegan sliced 'cheese')
2 tbsp Vegan Margarine (or more as needed)
Salt + Pepper
This is a picture to help you find the cheese in your local store (I bought this at Metro, so not too exotic).
Heat up a small pan on medium. Spread margarine on the outside portions of the bread and put one piece margarine side down in the heated pan. Layer with 1 1/2 piece of 'cheese' and the sliced avocado like this:
Layer the other 1 1/2 slices on the top and then the other piece of bread, margarine side up. Fry for 2-3 minutes, until cheese starts melting and then carefully flip. Cook for another 2-3 minutes, or until the cheese is all melted. Cut and serve with a dollop of ketchup or whatever you like for dipping.
*I had some leftover avocado from the 1/2 avocado, so I mashed it and put it on a piece of toast topped with salt and pepper (pictured at the back of the plate)
