Slice the biscuits into smaller pieces, then roughly tear them into irregular 1 to 1 1/2 inch pieces.
Scatter the biscuit pieces evenly over the filling, leaving small gaps so the filling can bubble between them. Lightly spritz the tops with oil.
Return the sheet pan to the 425°F oven and bake for 12 to 16 minutes, until the biscuits are puffed, golden brown and completely cooked through. Use the biscuit package directions as a guide, since brands and sizes vary.
Let rest for 5 to 10 minutes before scooping and serving.
