Just tried this idea tonight. Was in the mood for nachos, but not in the mood for the calories!
So....took some small tortilla shells that were "light" (called Rapiditas here in Argentina) and sprayed a teflon pan and just lightly toasted 2 of them. (I had pre-cut them w/ a pizza cutter into small triangles...to get the "nacho- effect") Added some "port salut" cheese when they were about toasted on the 2nd side and covered the tortilla w/ a saucepan lid to help it melt. Then cut up 2 small cherry tomatoes and part of an avocado and added a Tbsp. of salsa. (note: there is only one of the tortillas in the picture on a smaller plate - thought it looked pretty. I did toast 2 tortillas)
2 small tortillas - only 112 cal. for both!
"port salut" soft cheese (30 g) - 92 cal.
If a person wanted this for a regular meal, could add a bunch of lettuce, and more veggies for a taco salad. I had this more as a light dinner as I actually wasn't too hungry. Amazing!
