Bring a large pot of salted water to a boil. Cook the high-protein pasta according to package instructions until al dente. Reserve 1/4 cup of pasta water and drain the rest.
In a small mixing bowl, whisk together the honey, soy sauce, cracked black pepper, and chicken broth.
Season the cubed chicken with salt. Heat olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear until golden brown and cooked through (internal temperature 165°F/74°C). Remove chicken from the pan and set aside.
In the same skillet, add the onions and bell peppers. Sauté for 5-6 minutes until the vegetables are tender-crisp.
Add the minced garlic and cook for 1 minute until fragrant.
Pour the honey pepper sauce mixture into the skillet. Bring to a light simmer for 2 minutes.
Stir in the light cream cheese until fully melted and incorporated into the sauce.
Add the cooked pasta and chicken back into the skillet. Toss thoroughly to coat, adding reserved pasta water if the sauce needs thinning.
Garnish with red pepper flakes and additional black pepper before serving.
