To make the Green Apple Guacamole, combine the mashed avocados, apples, jalapenos, cilantro, lime juice and 1/2 tsp of salt in a small bowl. Set aside.
Lightly brush olive oil on both sides of the corn tortilla and cut into thin strips. Place on a baking sheet and lightly sprinkle with salt. Bake for about 9-10 minutes until crisp and golden brown. Remove from the oven and set aside.
Lightly season the fish on both sides with salt and pepper. To grill your fish inside, heat a grill pan that has been lightly brushed with olive oil over medium-high heat. Add your fish and cook for approximately 4 minutes. Using a spatula carefully turn your fish over and cook for 3-4 minutes more, or until the fish is done and flakes easily with a fork.
You can also grill the fish outside, but use a fish basket, or be sure to oil the cooking grates. Tilapia is delicate and falls apart easily.
To assemble, add approximately 1 cup of arugula to a bowl, top with 1/4 of the Green Apple Guacamole, and add one grilled fish fillet. Top with a few of the tortilla strips. Repeat with the remaining ingredients. Enjoy!
