Preheat the oven to 375 degrees. In a large bowl combine the ground beef, sun-dried tomatoes, basil, egg, breadcrumbs, garlic powder, salt, and pepper. Mix until evenly blended.
Divide the mixture into four equal portions and shape each into a small loaf. Wrap two slices of bacon around each loaf, tucking the ends underneath.
Place the wrapped loaves on a baking sheet and bake for 30 to 35 minutes until the internal temperature reaches 160 degrees and the bacon is browned.
While the meatloaves bake, bring the chicken broth to a boil in a medium saucepan. Whisk in the polenta and reduce heat to low. Simmer for 5 minutes, stirring often.
Stir the heavy cream, Parmesan, and butter into the polenta. Continue cooking for another 3 to 4 minutes until thick and creamy. Serve the meatloaves on top of the polenta.
