Fire your grill with enough briquettes to get it good and hot.
In a large bowl, mix the ground round, bread crumbs, lemon grass, shallot, chili paste, and peanuts. Season with salt and pepper. Form the meat into patties. Do not add the peanuts until you're just about ready to grill, otherwise they will get soggy.
Lightly oil the grate, then place the burgers on the grill. Cook for about three to five minutes per side.
Remove from the grill and sprinkle the burgers with lime juice.
