I found these delectable croissants on the Life with the Crust Cutoff website. Now if you haven't visited the website, let me tell you, the recipes you will find on this website are downright delicious. If you want to lose belly fat, you'll either have to skip many of her recipes altogether or adapt them to fit into your weight loss regimen.
Mix the mustard, honey and brown sugar together.
Spread the honey mustard mixture on each side of the four split croissants.
Place a slice of swiss on each half of the croissants.
Top the bottom half of each croissant with however much ham you like.
Place two halves back together.
Wrap in foil.
Place in the fridge for later or
Place in a 350 preheated oven for 10-15 minutes. Yum!
