watermelon and feta thing — dead simple

Right so this is barely even a recipe but I've had it three days running now and I'm not stopping. Watermelon, feta, a handful of mint, red onion sliced dead thin. Chuck it together. The bit that makes it though — a tiny drizzle of chilli oil and some toasted sesame seeds on top. That's it. Done. I know watermelon and feta is nothing new la, everyone's seen it. But the chilli oil is the thing. Picked up that habit from Bangkok, basically put it on everything for two years and never fully stopped. The heat against the cold watermelon is just... it works. Shouldn't need explaining. Verdicts: boss. Will keep making it until watermelons disappear from the shops.
