Beef tenderloin is one of the most tender and expensive cuts of beef. Ask your butcher to tie the tenderloin in 1-inch increments. If you can't find mushroom pâté in your grocery store, just leave it out--the recipe is delicious even without it.
Notes: First of all, you're going to want to use a Pain de Mie bread. Pain de Mie is just a type of slice packaged French bread and "la mie" refers to the soft part of the bread, which is called the crumb. It has sugar in it, which makes it sweeter than most French breads.
