Swiss Dijon Hamwich

I got the idea to use english muffins from The Biggest Loser Family Cookbook. I love ham and you will see a lot of onions in my recipes. Mmmmm..... onions. I've been putting together a bunch of different hot sandwiches lately with some of my favorite ingredients.Ingredients:
1 regular English Muffin* (120 calories)
2 ounces honey ham, sliced (60 calories)
1 cup raw onions, sliced or slivered (67 calories)
1 tsp Kraft Free Mayo (4 calories)
1 tsp dijon mustard
1 ounce shredded swiss cheese (45 calories)
1/2 roma tomato (9 calories)

Directions:
In non-stick pan, spray cooking oil and "I can't believe it's not butter" spray. Add onions and sautee until tender. Add ham and stir until ham is warmed through and beginning to brown. Toast the English Muffin and spread Free Mayo on one half and dijon mustard on the other half. Scoop onions and ham into a small mound in the pan, top with cheese and allow to melt. Scoop onions, ham, and cheese onto English Muffin, top with tomatoes and serve warm.
