When I lived in Taiwan, I would often get burgers (and a bacon danbing [kind of like a Chinese breakfast burrito but not really]) for breakfast at a chain called Beautiful and Breakfast. They put fried eggs on their burgers. That tasted great. I like to put salsa on eggs. I say try putting a fried egg and salsa on that burger. I bet it would be awesome. If you decide to not do that then try to find some fry sauce (a condiment popular in Utah) and spread that on the bun like it was mayo.
This thread convinced me to put salsa on my omelette.
I've done that many times before, it's quite good! But I'm still anti-salsa on burgers. I don't want toppings so easily falling out of my hamburger! May I recommend an egg instead on said hamburger? That's the wave of the future - slowly integrating breakfast into everything!!!
