Heat olive oil in a large skillet over med-high heat. Alternatively, preheat the BBQ to 425 F. Season chicken with salt & pepper, then add to the pan, sauteeing for 5 minutes per side. If grilling, grill for 4-5 minutes per side. Remove from heat and set aside.
Meanwhile, add almonds, walnuts, pumpkin seeds and maple syrup to a medium-sized skillet over medium-high heat. Cook for 5 minutes, stirring often, until mixture thickens and starts to solidify. Place onto a plate, let cool at least 5 minutes, then crumble.
Mix together ingredients under the dressing heading. Once chicken has rested for 5 minutes, slice chicken against the grain into bite-sized pieces.
Add spinach to a large bowl, along with strawberries, red onion and nut brittle.
When salad is ready to serve, toss with dressing, then divide among 4 salad bowls. Top with sliced chicken and goat cheese. Serve and enjoy!
