Cook the rice according to the instructions on the pack.
Whilst it is cooking, heat the oil in a non-stick pan and fry the onion for 1-2 minutes to soften, add the beef and fry for 4-5 minutes until browned on all sides. Sprinkle in the paprika and stir through the meat.
Reduce the heat, add the Simply Stir and heat through for 1-2 minutes, stirring well. Cook the courgettes in a little boiling water for 2-3 minutes until tender, drain.
Serve stroganoff over cooked rice with the courgettes.
