Yes, I KNOW it sounds odd, but please bear with me and please TRY this!
This is so simple, and trust me, it WORKS.
So, how did it come about?
Recently, at my parents for the weekend, my step-mum (a very good cook) put together a quick lunch of salamis, cooked meats, breads and .... watermelon. It worked.
And I thought back to a couple of years ago when I made some Thai-influenced little chicken burgers for a party, and I'd added a chunk of watermelon to them in place of a bun, just a little piece of watermelon skewered with a cocktail stick on top of the burger patty.
Oh and I ALSO thought back to days in Thailand, driving through a rural area when suddenly there would be sign up for gai yang, and you could see the chickens roasting on the spit, and we'd slam on the breaks and jump out.
Where the guy would come out his house, take the chicken down, get that big cleaver out and chop it into chunks (bone included) and bag it up to give you.
Where roast chicken is eaten dipped in sweet chilli sauce.
So, combine it all together and you've got watermelon chicken salad.
First time I made it I cooked a roast chicken and had the chicken warm with cold watermelon chunks and a good drizzle of sweet chilli sauce, with rice salad.
Since then I've griddled a piece of chicken to mix with watermelon and Thai sweet chilli sauce.
I've been camping in France and bought cooked chicken from the supermarket to mix with the watermelon and the sweet chilli sauce (I brought this with me as haven't found French supermarkets to have the diverse range of foods I take for granted now in London).
And every time I've made it, it's been good.
