Boil chickpea pasta in salted water according to package directions; drain and reserve 2 tablespoons of the pasta water.
Season the chicken breast with sea salt and black pepper, then pan-sear in a non-stick skillet over medium heat until cooked through.
Remove the chicken from the skillet, slice into thin strips, and set aside.
In the same skillet, add the olive oil and toast the panko breadcrumbs until they are fragrant and golden brown, then remove them and set aside.
Add the minced garlic to the skillet and sauté for 30 seconds until aromatic.
Toss the cooked pasta, sliced chicken, reserved pasta water, and lemon juice into the skillet with the garlic.
Stir in the parmesan cheese and fresh parsley until the pasta is evenly coated and glossy.
Transfer to a plate and top with the toasted breadcrumbs before serving.
