Preheat your oven to low broil.
In a skillet, heat the olive oil over medium heat.
Add the spinach and sauté until just wilted.
In a bowl, mix the ricotta and mozzarella cheeses.
Stir in the garlic powder and Italian seasoning.
Combine the cooked spinach with the cheese mixture.
On a flat surface, lay two slices of deli ham overlapping.
Spoon the filling onto the ham and roll it up tightly.
Arrange the roll-ups in a baking dish in a single layer.
Broil for 5 minutes, or until golden brown and melty inside.
