Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat olive oil in a large skillet over medium heat and sauté the chicken until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the diced yellow onion and minced garlic, sautéing until fragrant and translucent.
In a blender, combine the roasted red peppers, Greek yogurt, and smoked paprika, blending until the mixture is completely smooth.
Pour the red pepper sauce into the skillet with the onions and garlic, stirring over low heat until warmed through.
Add the cooked pasta, sautéed chicken, and baby spinach to the skillet, tossing gently until the spinach is wilted and the sauce is creamy.
