Preheat oven to 400°F and line a small baking sheet with parchment paper.
Toss cherry tomatoes with 0.5 teaspoons of olive oil, a pinch of sea salt, and a pinch of black pepper on the baking sheet.
Roast the tomatoes for 15 minutes or until they are blistered and starting to release their juices.
Season the chicken breast with the remaining sea salt and black pepper, then grill or pan-sear over medium heat for 6-7 minutes per side until cooked through.
Let the chicken rest for 5 minutes before slicing it into thin strips.
Boil the chickpea penne pasta in salted water according to package directions, then drain and reserve 2 tablespoons of the cooking water.
In the same pot used for the pasta, heat the remaining 0.5 teaspoons of olive oil and minced garlic over low heat for 1 minute until fragrant.
Add the cooked pasta, roasted tomatoes, sliced chicken, lemon juice, fresh basil, and fresh parsley to the pot.
Toss everything together gently, adding the reserved pasta water if needed to create a light sauce, and serve immediately.
