Roast Beef Sandwich with Melted Cheese and Caramelized Onions

I wish this photo could capture how delicious this sandwich is. I made a few attempts at photographing this, but the photo can’t capture how sweet these caramelized onions are and how perfect they taste with yesterday’s leftover garlic infused roast beef and melted Swiss cheese.

Father’s Day is coming up and I’m trying to think of dishes that would make Dad happy. For those of you who are Pinterest obsessed, I made a Skinny Father’s Day board and pinned recipes I think Dads would love. My husband loves caramelized onions, I can’t say I blame him. I never
knew just how good they were until I met him; he makes them all the
time. The onions shrink to about half their size when they slowly cook
down, and as they turn golden in color they turn sweet and delicious. They are great over burgers too, I make them with a lot less oil than he does with great results.

I don’t east sandwiches often, maybe once a week. But when I do eat a sandwich, my bread of choice is a fresh baked whole wheat French or Italian bread from the bakery because it’s generally made with no fat and I love a crispy fresh baked loaf.
