Heat a wok over high heat until hot. Drain any marinade from the pork. Add 2 teaspoons of oil to the hot wok and swirl to coat Add one-third of the pork, making sure each piece comes in contact with the hot work. Stir-fry for 1 minute until seared. Remove to a plate.

Wipe the wok clean and heat again over high heat until hot and add the remaining oil. Add the Broccolini®, Fioretto® and Minicaps® and stir fry for 2 minutes until almost tender. Return the pork to the wok, pour over the sweet and sour sauce and stir-fry for 1 minute until hot. Serve with rice.
