I almost always have boneless/skinless individually frozen chicken breasts in the freezer.  I throw them in a pyrex dish with garlic salt and italian seasoning with the oven at 350 while I prepare a salad or veggie and brown rice.  If I want to switch it up a little bit, I might put a layer of pepperonii and melt some mozzarella cheese on top.  (my husband does a low carb diet so we always have pepperoni in the house for him to snack on)  (Oh, I can do this much later than 3:30.)
