Heat the oil in a pan or in a wok. Fry the garlic and ginger for about 30 seconds while stirring. Add paprika and fry for 3 minutes. Take the meat out of the soy sauce and add it, fry brown all around for about 5-6 minutes. Pour the soy sauce and black bean sauce over the meat, bring to the boil and simmer for 1 minute.
