Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While pasta cooks, heat olive oil in a large skillet over medium heat and add the diced chicken breast seasoned with sea salt and black pepper.
Cook the chicken for 5-6 minutes until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the cherry tomatoes and minced garlic, sautéing for 4-5 minutes until the tomatoes begin to burst and release their juices.
Reduce heat to low, add the dried oregano and crumbled feta cheese to the skillet, stirring gently until the cheese softens into a creamy sauce.
Drain the pasta, reserving 2 tablespoons of pasta water, and add both to the skillet along with the cooked chicken.
Toss everything together until well-coated, then garnish with freshly chopped basil before serving.
