Mix fajita seasoning ingredients together and rub onto the flank steak, making sure to cover all sides and edges.
Heat 1 tbsp olive oil in a skillet. Cook steak 4–5 minutes per side or until the internal temperature is 55°C (medium). Rest 5 minutes, then slice thinly against the grain – slicing against the grain on a flank steak is important, it will ensure that you get a beautiful, tender steak.
2. Char-Cook Veggies
In the same skillet, without cleaning it (unless it’s particularly charred and dirty) cook capsicum and onion in a single layer for 1–2 minutes to develop a light char – don’t overcook as you still want to have a little bite.
3. Serve
Arrange steak and veggies on a platter or skillet and serve with warm tortillas or coriander lime rice and your favourite toppings.
