How to Make It
Mix all the dressing ingredients together until combined, and set aside.
Heat a frying pan or grill over medium-high heat. Toss the shrimp in the oil, and cook until they are pink throughout. (At this stage, you could leave the shrimp in the dressing until you're ready to assemble the salad.)
In a large bowl, mix the papaya slices, radishes, lettuce and herbs. Toss in the shrimp, and drizzle over the dressing.
