Peel sweet potatoes and slice into rounds about 1cm thick.

Pan fry the sweet potatoes in 4 tbsp olive oil until they have a nice coating. Easier to do in batches.

Arrange as a layer in the slow cooker.

Next add the chicken to the pan and upto 2 more tbsp of olive oil. Get a nice brown coat but don't cook the chicken.

Place the chicken on top of the potatoes.

Start adding all the ingredients. Chopping the garlic.

For the lemons. Zest and juice both.

Flip the chicken over and move around a little to mix the sauces better.
