How do you like your hamburger?

This is the last weekend of the month, so get out and grill some burgers to celebrate May as National Hamburger Month.

This month the hamburger chain, White Castle, turns 90 and they were the one's who reportedly created National Hamburger Month as a promotional gimmick in 1992.

There sure are a lot of ways to prepare and build a hamburger.

First of all, you can have them cooked from rare to well-done, with cheese or without, and what you can add on top is only limited by your imagination.

Popular condiments include ketchup, mustard, pickles, mayo, lettuce and tomato. Some of my favorite extras are bacon and guacamole.

What is your perfect combination?
