Oregano is a very strong spice, so I used Italian Seasoning instead. I also added 2 TBS olive oil, instead of teaspoons, for a silkier texture and better melting. With these changes, it was excellent.
I used cheap french bread baguettes that I bought off the clearance rack. The butter mixture called for in this recipe was just enough for a thin coating on four "sandwich" sized baguettes, both sides. This was quick to assemble and the boys really liked it.
