Bring a medium pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While 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. Add the chicken and cook until golden brown and cooked through, about 5-7 minutes.
Add minced garlic and baby spinach to the skillet, sautéing until the spinach is wilted.
Reduce heat to low and stir in the tomato puree. Let it simmer gently for 2 minutes.
Remove the skillet from heat and stir in the Greek yogurt and freshly chopped basil until the sauce is smooth and creamy.
Drain the pasta, reserving a splash of pasta water, and toss the pasta into the skillet with the sauce.
Mix well, adding a tablespoon of pasta water if needed to reach your desired consistency, and serve immediately.
