I need help with Nutrition Info

lmkelly679

I made this last night and ate leftovers tonight (it's amazing by the way!) http://caloriecount.about.com/low-calorie-stuffed-peppers-ground-recipe-r19746

What i did differently was i didn't use carrots and i added about .75 of a slice of 2% milk yellow cheese on each pepper and i used a little more onion and garlic than needed. The nutrition info says its 379 calories per serving but when i entered all the ingredients on MFP it came out to 228 calories. I just wanted to see if anyone else could come up with the same number as me, I knew id come out with a different number but thats a very big difference! Any help would be great!
