The new pizza sliders at Pizza Hut (handout photo)

Fast-food giants McDonald’s and Pizza Hut are thinking small after the Super Bowl, with new menu offerings that take after the small plates, tapas and portion-controlled craze.

McDonald’s this week is adding seafood for the first time to its Happy Meals with its Fish McBites. The seven small pieces of Alaska pollock — which are certified as sustainably sourced — contain 170 calories.

The limited time offer will coincide with Lent, which begins next week, and is made with the same fish used in McDonald’s Filet-O-Fish sandwiches. The Fish McBites are also available on the regular menu in other sizes.

In another short-term promotion, Pizza Hut debuted pizza sliders following Sunday’s football game. The mini-pizzas are 3.5 inches across, compared to the 6-inch diameter of a standard Pizza Hut personal pie.

Customers can pick up nine sliders – with three combinations and up to three toppings each – for $10 or three for $5. Pizza Hut is giving away free samples of the small pizzas from 4 to 7 p.m. local time on Tuesday.
