Start by cooking quinoa according to package instructions. In a separate bowl, mix together diced pineapple, chopped mint leaves, and a squeeze of lime juice. Once the quinoa has cooled, toss it with the pineapple and mint mixture. You can also add additional ingredients like chopped cucumber or bell peppers for extra crunch. Finish with a drizzle of olive oil and season with salt and pepper to taste. Serve chilled and enjoy!
