Divide ground beef into 4 equal parts and form hamburger patties, make sure to read my "tips for a better burger". Stack into a tower (separated by wax paper) or put on a plate in a single layer and put into the freezer. Freezing will congeal the beef together and give you less probability of patty breakage (sounds official, huh?).
While they congeal, place sun dried tomatoes, roasted red peppers and a dash of fine sea salt into a mini food processor and blend until a paste forms. If you are using sun dried tomatoes that were not packed in oil, you may need a teaspoon of extra virgin olive oil to create the right consistency.
Remove hamburger patties from the freezer and season with salt and pepper. Do not over season with salt. It can dry up the natural juices resulting in dry patties.
Heat the grill to medium-high heat. Grill the burgers for 2 minutes on each side, then move them to a lower-heat area of the grill. Cook another 2-3 minutes for medium-rare burgers, 3-4 minutes for medium, or 5-6 minutes for well-done burgers. Remove and allow to rest for 3-4 minutes before assembling.
Toast Kaiser rolls in the over or toaster if desired.
Assemble your gigantic burger! Take one patty, slather it with the sun dried tomato paste, a few leaves of basil and a slice of mozzarella cheese, top it off with the other side of the bun!

For balsamic reduction, please 1/4 cup balsamic vinegar and 1 teaspoon in small sauce pan for 5 minutes on low heat. Mixture will reduce and become syrupy after cooling.
