Start by bringing a pot of water to a boil, then add the whole wheat pasta and cook according to the package instructions until al dente. Drain and set aside.
While the pasta cooks, pat dry the chicken breast and season both sides lightly with salt and pepper.
Heat a non-stick skillet over medium-high heat and add the olive oil. Once the oil is hot, add the chicken breast.
Sauté the chicken for about 4-5 minutes per side, or until golden brown and cooked through. In the last minute of cooking, add minced garlic and squeeze in the juice from half a lemon to create a fragrant pan sauce.
Remove the chicken from the skillet and let it rest for a couple of minutes before slicing it into thin strips.
Dice the fresh tomato and roughly chop the basil. Toss these with the drained whole wheat pasta. Adjust seasoning with extra salt, pepper, and a drizzle of lemon juice if desired.
Plate the pasta, then top with the sliced chicken. Spoon any remaining pan sauce over the top and garnish with the fresh basil.
Serve immediately and enjoy this bright, flavorful dish.
