Bring a large pot of salted water to a boil and cook the whole wheat penne according to package directions until al dente.
While the pasta cooks, place the broccoli florets in a steamer basket over boiling water and steam for 5-6 minutes until tender-crisp.
Season the chicken breast with salt, pepper, and Italian herbs.
Heat 1 tablespoon of olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until fully cooked and golden brown.
Remove the chicken from the skillet and let it rest, then slice it into strips.
In the same skillet, add the remaining 0.5 tablespoon of olive oil and sauté the minced garlic for 1 minute until fragrant.
Lower the heat and whisk in the heavy cream and parmesan cheese, adding a splash of pasta water if needed to reach a silky consistency.
Toss the cooked pasta into the garlic sauce until well coated.
Plate the pasta and top with the sliced seared chicken and steamed broccoli.
