Bring a large pot of salted water to a boil and cook the brown rice pasta according to package instructions until al dente.
Reserve 2 tablespoons of the starchy pasta water before draining the noodles.
Season the chicken breast with half of the sea salt and black pepper on both sides.
Heat the olive oil in a large skillet over medium heat and cook the chicken until golden and cooked through, approximately 6 minutes per side.
Remove the chicken from the skillet, let it rest for 3 minutes, then slice into thin strips.
In the same skillet, add the minced garlic and sauté for 30 seconds until fragrant but not browned.
Reduce the heat to low and whisk in the Greek yogurt, parmesan cheese, lemon juice, and reserved pasta water until a smooth sauce forms.
Add the cooked pasta and sliced chicken back into the skillet, tossing gently to coat every strand in the creamy sauce.
Garnish with fresh chopped parsley and the remaining salt and pepper before serving warm.
