Grilled Loaf

This recipe is an OLD one I haven't made in a very long time.  It came out one of those (I now think horrible) little cookbooks you find in the grocery checkout line. Despite it's origins, this is a tasty and quick meal.  The original fillings lost in time, but this is ours:)
Grilled Loaf

1    loaf of fresh bread not cut
1/4 c  of pesto sauce (or more if you like)
1/2 lb Sliced deli turkey
1/4 lb Salami
1/2 lb Provolone Cheese
1    Onions,Caramelized
1/4 c  Roasted Red Pepper,Sliced And Patted Dry

1.Slice top off of the bread
2.Hollow out the loaf leaving a ½" wall
3.layer the fillings starting with the meat, then cheese, then sauce,
then veggies. Repeat ending with cheese

Wrap in foil and bake in a 250 oven for about an hour
Can also be thrown on a grill and cooked that way over indirect heat
for about 30 minutes
Cooking time will vary based on size and shape of bread.  Even a cool
center wouldn't be dangerous to eat, but you want warm melted cheese
center
You can vary all the ingredients as long as you make sure that the
veggies and other 'wet' ingredients aren't going to release a lot of
liquid (ie precooking them) and not having only meat and cheese (ie
include pesto, mustard etc...)
I have made these with Ruben ingredients,  Cuban ingredients, roast beef
and horseradish, and many others.
[Note:  I like Cuban and Ruben fillings the best ]
