Preheat the oven to 400F. Spray a baking sheet (or two) with cooking spray and set aside.

Halve or quarter the potatoes so that they are roughly the same size. In a medium bowl, toss potatoes with 4 tsp. of olive oil and sprinkle with salt and pepper. Spread onto prepared baking sheet and bake in preheated oven for 20 minutes.

While potatoes are cooking, transfer green beans to the bowl used for the potatoes. Toss with remaining 2 tsp. olive oil and sprinkle with salt and pepper. Set aside.

In a large bowl, use clean hands to mix together ground beef, ground turkey, breadcrumbs, garlic powder, and 1/2 c. BBQ sauce. Mix until well combined.

When potatoes are ready, remove from oven and mix. Push to one end of the baking sheet (if only using one baking sheet). Add green beans in the center. Form 6 mini meatloaves, and place on the last third of the baking sheet.

Return baking sheet to oven and continue cooking for another 25 minutes, until meatloaves are cooked throughout. Remove baking sheet from oven and adjust oven temperature to broil. Brush each meatloaf with 1 - 1 1/2 Tbs. BBQ sauce. Return baking sheet to oven and broil for 3 minutes.

Remove baking sheet from oven and allow to rest for 5 minutes before serving.
