Gather and prepare your ingredients.
Place the garlic, Chinese five spice, soy sauce, maple syrup, tomato puree and sesame oil into a medium bowl and whisk to combine. Pour over the chicken, toss to coat and leave to marinade for 2-3 minutes.Slicing the chicken finely means it doesn't take long to marinade.
Place a frying pan over medium high heat and add the olive oil. Once hot add the chicken and cook for 5-6 minutes, turning occasionally, until the flesh is completely opaque, turning dark brown in places and the marinade has reduced and turned sticky.
Slice open the baguettes. Fill with lettuce, cucumber, chili, avocado chicken, coriander, and drizzle with sriracha.We've served ours with our 'Quick Pickled Radish and Carrots.'
