Marinate the chicken breasts with lemon juice, olive oil, salt, and minced garlic cloves for at least 10 minutes.
Bring a large pot of salted water to a boil and cook the protein pasta according to package instructions until al dente.
While the pasta cooks, heat a skillet over medium heat and cook the marinated chicken breasts for 6-7 minutes per side or until fully cooked and golden brown. Remove and let rest.
In a bowl, whisk together the egg, bone broth, and shredded parmesan cheese to create a silky sauce.
Slice or cube the cooked chicken.
Drain the pasta and return it to the pot; stir in the high protein pesto and the egg mixture over low heat to gently coat the pasta and create a creamy texture.
Add the cooked chicken pieces to the pasta and toss everything until well combined and heated through.
Serve immediately, garnished with extra parmesan or fresh herbs if desired.
