1. Prepare an outdoor grill and heat it to hot. In a
large bowl combine the beef and curry paste and mix until just blended.
Allow the meat to flavor, refrigerated, for at least 30 minutes and up
to 2 hours.
2. Meanwhile, spread the tomato slices on a large plate
and season them with the salt and pepper. Form 4 patties from the meat
mixture about 1 inch thick.
3. Spray the grill grid with nonstick cooking spray and
grill the burgers, turning once, until done, about 4 minutes per side
for medium rare. Alternatively, heat a heavy grill pan or sauté pan,
spray it with nonstick cooking spray, and grill the burgers. The burgers
can also be broiled in a preheated broiler about 3 inches from the heat
source. Make sure the burgers are cooked through by cutting into one and
checking for doneness.
4. Place 2 tomato slices on each bun bottom, add the
burgers and top with the remaining tomatoes. Finish with the bun tops
and serve.
