Cut the chicken in half lengthwise so you have 4 thinner pieces. Season them with the garlic powder and some salt & pepper.
Add the oil and 1 tablespoon of the butter to a skillet over medium-high heat. Let the pan get hot for a few minutes.
Cook the chicken for 5-6 minutes/side or until golden and cooked through (165F). Transfer to a plate and cover with foil to keep it warm.
Reduce the heat to medium. To the same skillet, add the rest of the butter, the Dijon mustard, garlic, Italian seasoning, sun-dried tomatoes (chop them if you want them a little smaller), and the contents of the risotto package. Cook for 1 minute, stirring nearly constantly.
Add in the water and wine, and give it a good stir. Increase the heat to high, and once it starts to boil, reduce the heat to medium-low and simmer, uncovered, stirring occasionally, for about 15 minutes or until the liquid has absorbed and the rice is al dente (tender but still with a bit of a bite). Note: every stove/pan varies, so if the liquid has evaporated before the time has elapsed, turn the heat down and add a splash more water or wine.
While the risotto is cooking, cut the chicken into bite-size pieces.
Take the skillet off the heat and stir in the parmesan and basil. Top with the sliced chicken and serve immediately.
