Pat the chicken breast dry, season with sea salt and black pepper, and dice into bite-sized pieces.
In a small bowl, whisk together the almond butter, coconut aminos, rice vinegar, and grated ginger until smooth.
Heat sesame oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear until golden and cooked through, about 5-6 minutes.
Stir in the sliced mushrooms and minced garlic, sautéing until the mushrooms are tender and fragrant.
Add the rinsed noodles to the pan and toss for 2-3 minutes to heat through and evaporate excess moisture.
Pour the savory sauce over the mixture and add the baby spinach, tossing until the spinach is wilted and the sauce coats everything.
