In a Dutch oven, place the stew beef, bouillon cubes, salt, crushed red pepper, chili powder, chili flakes, curry powder, and water. Stir and bring to a rapid boil. Reduce the heat and simmer, covered, for 1 hour. Cut the bacon into small pieces and fry in a skillet until all of the fat is rendered. Remove the bacon from the skillet and reserve. Saute the greens and the onions in the bacon fat for 4 minutes, stirring constantly. Add the sauteed greens and onions along with the tomato puree, reserved bacon, and peanut butter to the stew. Stir and simmer, covered, for 1 hour. Serve with rice.
