Baste your bundt pan with olive oil; season it with oregano.
Cut-up a handful of pepperoni slices, keeping some close by to cut up if you run out.
Open up the biscuits cans, and slice your biscuits in half.
Thin out the biscuit half, as thin as you can.
Add some pepperoni pieces and cheese into the center of the biscuit half, and fold the sides inward, pressing seams together, rolling into a ball; set aside.
Continue with each biscuit half until all are filled with pepperoni and cheese.
In a bowl, add oil, oregano, salt, pepper, and garlic; mix well.
Roll each ball into the bowl until well coated.
Place each oil coated ball into the bundt pan.
Bake for 30-40 minutes, or until top is golden brown.
Remove from oven, flip onto a large serving plate.
