Bring a medium pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, pat the chicken breast dry and season both sides with sea salt, black pepper, and dried oregano.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden brown and cooked through.
Remove the chicken from the pan, let it rest for 2 minutes, then slice into thin strips.
In the same skillet, reduce heat to medium and add the minced garlic, sautéing for 30 seconds until fragrant.
Add the cooked pasta, baby spinach, lemon juice, and lemon zest to the skillet, tossing gently until the spinach is just wilted.
Return the chicken to the pan and toss everything together to coat in the light lemon sauce.
Divide the pasta into a bowl and garnish with freshly chopped parsley before serving.
