Cook the pasta according to package directions. Toss with 1 tbsp olive oil and set aside.
Make the sauce: Add cherry tomatoes to a pan with 1 tbsp olive oil. Cook until soft and burst. Break tomatoes to release juices, creating a thick sauce.
Add the veggies: Add sweet corn and zucchini to the pan with the tomatoes. Sauté for a few minutes until zucchini is softened.
Stir in minced garlic for the last minute of sautéing until fragrant.
Add lemon juice, salt, and pepper to taste. (Optional: Add a splash of cream for richness).
Pan-fry the chicken: Coat chicken pieces in flour mixture (flour, salt, pepper). Shake off excess.
Heat 1 tbsp olive oil and 1-2 tbsp butter in a separate large skillet over medium-high heat. Add chicken and cook for a few minutes per side until golden brown and cooked through.
Put it all together: Add the cooked pappardelle pasta and chicken to the pan with the sauce and vegetables. Toss to combine and serve immediately.
