In a heavy stew pot, brown onion in oil until golden yellow. Add meat, salt and pepper. Saute over medium heat until meat loses its red color, then cook over low heat for 15-20 more minutes. With two stones or a mortar and pestle, grind or pound the chili and garlic together; add them; zith curry powder, to the pot. Continue simmering until meat is tender, adding the beans about 15minutes before serving. When the flavors have blended, transfer to a serving dish and drizzle with lemon juice.
