I have this deal when I'm eating a meal that I really enjoy- when I start to get full I begin to assemble what will me my last, most perfect bite. It includes what I deem to be the best proportions of all the parts of my meal layered together on my spoon or fork.
This is my perfect bite of taco fixins. I make and eat a ridiculous amount of tacos and I love to end it this way. The problem is, it's usually so delicious that I go back for another taco.
