Tuna Salad in Ramekins

Ingredients --  Pescaterian / Ovo-Lacto Vegetarian
This is more of a suggestion, it's ludicrously simple, just an idea when brainstorming lunch.
Mix together a hearty Tunafish salad with your favorite add-ins, perhaps going a little light on the Mayonnaise compared to making a sandwich.  Fill oven-proof ramekins with the mixture and cover the top with shredded cheese.  Certainly these could be served cold as-is, but for variety you might warm them in the oven at 325 degrees F for 20 minutes instead.  (That's why I advise light on the mayo here -- so that the tuna cooks better and is less liquid.)  Some people enjoy add-in such as cranberries or frozen peas in a tuna salad, but those are less keto than the recommended ingredients.
