Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Place the cherry tomatoes on the baking sheet, drizzle with 1 teaspoon of the olive oil and a pinch of salt, then roast for 12-15 minutes until they begin to burst.
While tomatoes roast, bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
Season the chicken breast with half of the salt and pepper, then sauté in a skillet over medium heat with 1 teaspoon of olive oil until golden and cooked through, about 5-6 minutes per side.
Remove the chicken from the pan, let it rest for 2 minutes, then slice into thin strips.
In the same skillet, add the remaining teaspoon of olive oil and the minced garlic, sautéing for 1 minute until fragrant.
Add the cooked pasta, roasted tomatoes (and their juices), sliced chicken, and remaining salt and pepper to the skillet.
Toss everything together with the fresh basil and lemon juice until well combined and serve immediately.
