Simply The Best Hamburger

• Ground Beef, 80/20 preferred, you can also mix in other red meats if you like but there's something to be said for the simplicity of an all beef burger, about 1/3 of a pound formed into a nice patty
• Onions or shallots, your choice, sliced
• Tomato, sliced
• 2 Serrano Peppers, roasted and sliced
• Green leafy vegetable of your choice I like spinach a lot so I use that pretty much anything will work
• Cheese or cheeses of your choice, I use a lot of different kinds
• Mushrooms (optional)
• Pickles (optional)
• Bun, lot of options, use what you like
• Salt
• Pepper
• Worchestershire Sauce

1. Season the patty with salt and pepper and worchestershire to taste.
2. Preheat oven to 375 degrees. Roast serrano peppers for ten minutes, then turn over, at the ten minute mark put buttered bun in oven to toast and start cooking burger. Peppers should be done roasting at about 15-16 minutes. Cook burger on medium heat in cast iron skillet in oil you like. Add onions and mushrooms to same pan as burger and cook onions til soft and brown and mushrooms until tender and brown.
3. Ensure that as you cook your burger you DO NOT press on it, all this does is squeeze juices out and lose flavor. Cook til you are happy with its doneness, I like mine a bit on the rare side, add your cheese to the top of the patty for the last 2-3 minutes so it can start melting. By now your peppers and buns should have been long toasted. On your bottom bun make a bed with your onions and mushrooms, then add your patty, then your serranos, tomatoes, spinach, and on the very top your pickles. Every time I make a burger it seems like it ends up too tall to eat easily, but it tastes good.
