Preheat your oven to 400F. Then, add egg, coconut flour, grated apple, grated yellow onion, garlic, sage, thyme, salt & pepper to a large bowl. Whisk until combined. Add in the ground chicken and use your hands to gently incorporate, without over-mixing. Set aside.
1 lb ground chicken, 1 large egg, 2 tbsp coconut flour, ⅓ cup grated apple, ¼ cup grated yellow onion, 3 garlic cloves, 1 tbsp finely chopped fresh sage, 1 tsp kosher salt, ½ tsp dried thyme, ¼ tsp black pepper
Add sweet potato, brussels sprouts and chickpeas to an extra-large baking sheet (21 x 15"). If you don't own one this big, split it between two normal-sized baking sheets. Then, drizzle avocado oil and seasonings over the top. Toss to coat and then spread out evenly on the baking sheet(s). There should be minimal overlap.
10 oz shaved brussels sprouts, 1 medium sweet potato, 1 can chickpeas, 2 tbsp avocado oil, 1 tsp kosher salt, 1 tsp italian seasoning, ½ tsp garlic powder, ½ tsp onion powder, ½ tsp smoked paprika, ¼ tsp black pepper
Scoop out 2 tbsp of the ground chicken mixture and roll into a ball. Then, nestle the meatballs onto the baking sheet. It should make about 16-18 meatballs. Transfer to the oven and cook for 20 minutes. Optionally, switch your oven to broil for a few more minutes to get a nice golden finish on the meatballs and the veggies.
Meanwhile, add all maple tahini sauce ingredients to a small bowl and stir until combined and smooth. Continue to add more water as needed to get it to your desired consistency. It thickens up as it sits.
¼ cup tahini, 1 tbsp maple syrup, 1 tbsp white wine vinegar, 1 tbsp fresh lemon juice, 1 tbsp water, ½ tsp kosher salt, ¼ tsp garlic powder, ¼ tsp black pepper
Drizzle the maple tahini sauce over the sheet pan. Top with chopped parsley, if you'd like. Enjoy!
