Start by heating a tablespoon of olive oil in a skillet over medium heat.
Sauté garlic and chilli for about a minute, just until they become aromatic.
Add the prawns, seasoning them with salt and black pepper, and cook until they turn pink and opaque, about 3-4 minutes per side. Once done, set them aside.
In a large mixing bowl, whisk together the remaining olive oil and fresh lime juice. Season the dressing with salt and pepper.
Add the diced avocados, white beans, halved cherry tomatoes, and chopped cilantro to the bowl, giving everything a gentle toss to ensure it's coated in the dressing.
Arrange the mixed salad greens on serving plates or a large platter.
Evenly distribute the avocado and bean mixture over the greens.
Top the salad with the garlic and chilli prawns, drizzling any remaining dressing over the top.
