Preheat your oven to 400°F (200°C).
In a large mixing bowl, combine the olive oil, garlic powder, paprika, oregano, salt, and black pepper. Mix well.
Add the pork chops to the bowl and coat them thoroughly with the marinade.
On one side of the baking sheet, arrange the pork chops in a single layer.
On the other side of the baking sheet, toss the broccoli florets and halved baby red potatoes with any remaining marinade. Spread them out evenly.
Place lemon slices on top of the pork chops and vegetables for added flavor.
Bake in the preheated oven for about 25-30 minutes, or until the pork chops reach an internal temperature of 145°F (63°C).
If desired, you can broil the dish for an additional 2-3 minutes for a crispy finish.
Remove from the oven and let the pork chops rest for 5 minutes before serving.
