Add the free-range chicken thighs to a large bowl. Add the all-American Spice Blend and season with salt and pepper. Drizzle with olive oil and toss to coat the chicken breast. Set aside.
Roughly chop the cos lettuce. Finely slice the Roma tomato.
Heat a drizzle of olive oil in a large frying pan (with a lid) over a medium-high heat. Cook the chicken thigh for 2 minutes on each side, or until golden
Add the tomato paste and warm water (for the chicken), season with a pinch of salt and pepper and mix well. Reduce the heat to low and cook, covered, for 8-10 minutes, or until the chicken is cooked through TIP: use aluminium foil if you don’t have a frying pan with a lid. Remove the lid and simmer for a further 3-4 minutes or until the sauce has begun to thicken. Shred the chicken using two forks and drain off the excess liquid.
Meanwhile, place the bake-at-home burger buns directly onto the wire racks and bake for 3 minutes, or until heated through. Remove the buns from the oven and slice in half.
To assemble the burgers, spread a layer of the smokey aioli over the base of each bun. Top with the cos lettuce, shredded chicken and some slices of Roma tomato. Enjoy!
