How many calories do you have left?
You can either eat something delicious and healthy or just eat the Pizza Hut and use extreme portion control. A slice of pizza and a salad could be under 300 calories, for example.
Me, I like to "spend" my calories on delicious, high quality food, not "junk" food, so it wouldn't even be a temptation for me.
Whole Foods makes a HUGE gourmet, quality pizza with any and all toppings for under $20.00 and THAT is worth the calories to me!
