Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the sweet potato into thin matchsticks and toss them in a bowl with the olive oil, garlic powder, and half of the sea salt.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes, flipping halfway through, until edges are golden.
Season the chicken breast with the remaining sea salt and the black pepper.
Grill or pan-sear the chicken over medium heat for 6-7 minutes per side until the internal temperature reaches 165°F.
In a separate small skillet, cook the turkey bacon until it reaches your desired level of crispness.
Toast the sprouted grain bread slices until they are lightly browned.
Mash the avocado in a small bowl and spread it evenly across one slice of the toasted bread.
Assemble the sandwich by layering the lettuce, tomato slices, grilled chicken breast, and turkey bacon between the bread slices.
Cut the sandwich diagonally and serve immediately alongside the hot sweet potato fries.
