I'll add a breakfast sandwich
WW English Muffin
One egg or two egg whites
Slice Cheese (classic american single makes it just like McD's, only less evil)
Toast Muffin
Microwave Egg in a small bowl. I have a couple of ramekins that are about the same diameter as an English Muffin
Slap Muffin, Egg and Cheese together
I often add fresh tomato and onion, and sometimes I only toast the inside of the muffin, then smash the sandwich in the foreman grill to make an egg & cheese panini. Easier to hold while driving to work, too (grin)
Oh, and I also make grilled cheese w/ tomato and onion inside. With really sharp cheddar this is heaven.
WW bread, smear hummus, smear a triangle of laughing cow on the other half, add lettuce, tomato, onion. With lower-calorie bread this is pretty low cal.
Quesadilla's count? Everyone knows how to make those

I make a veggie BLT w/ veg bacon. I hate mayo, and w/ enough cheese I've never missed it.
