I love to eat Avocado Sandwich! It's quite good, especially when I don't feel like having a fat steak. I guess it's a healthier alternative. Hehehe! It usually takes me a minute to put one together... sometimes a lot less. The pictures are pretty much self explanatory.

I guess when dealing with Avocado you have to be quick otherwise if you leave it too long out in the open after removing it from its shell it starts to oxidize, which of course changes its color to a very unpalatable black or darkish brown. Plus if you can get it into a sandwich quick enough you could still catch that fresh avocado scent. YUM! :)
