Rather than cutting up your whole loaf of french bread and buttering each piece individually, this is how I do it...(and yes, I learned it from my Mom...thanks Mom!)...
Slice your loaf open the long way (into 2 big pieces). Butter both sides and garlic salt. Then broil with the butter facing up.
After toasting (broiling), put the loaf back together...
Now cut them into as wide of slices as you desire (these ones were thin). (You will be cutting 2 slices at he same time)...
There you go...faster easier...practically the same result...
