Tuna Grilled Cheese

2013 Kids Recipe Challenge winning recipe: 2nd Place!

Brantford’s Clairise loves that this is fun to make and has lots of gooey cheese.  

Warm and comforting, grilled cheese sandwiches are always a big hit with everyone in the family. Look for light tuna such as skipjack since it is a great source of protein and usually lower priced than white tuna.  

Preparation Time: 10 minutes

Cooking Time: 5 minutes

Makes: 2 sandwiches


  1. This sandwich might be a bit messy to eat, but it’s tasty and colourful with the green baby spinach and bright red tomato.
  2. Put leftovers away within 2 hours or sooner if they are in a warm location. Reheat leftovers to an internal temperature of 165°F (74°C). Discard uneaten leftovers after they have been reheated.
