Halve cherry tomatoes, and add to a large serving bowl. Depending on the cucumber’s thickness, slice or chop so that pieces are similar in size to the cherry tomato halves, and add to the bowl.
Chop watermelon to a similar size, and add to the bowl.
Add the baby mozzarella balls, and add them to the bowl, along with the juice of your lime, the basil leaves, a big drizzle of olive oil, a big pinch of flaky salt & pepper, and a sprinkle of red pepper flakes.
Use a serving spoon to gently toss it all together, then drizzle with a bit more olive oil and serve.
