Heat the olive oil in a large skillet in medium heat.
Add the potatoes and adjust the heat to the lowest setting, allowing them to pre-cook for a few minutes.
Remove the potatoes and let them cool in the fridge for a few more minutes.
Turn the heat up to high and add the potatoes back to the pan.
Fry until crispy and golden.
Transfer the potatoes to a plate lined with paper towels to cool, and sprinkle with garlic powder, onion powder, and salt to taste.
To serve, drizzle the bravas sauce over the potatoes.
Using the same oil, crisp the prosciutto like bacon.
In the bottom of the dish, layer the potatoes, crispy prosciutto, and Manchego. Top with the Fresno peppers and parsley for garnish.
