This pie is one of those rare recipes that tastes like it came from the oven while being cooked entirely on the stovetop. It is an excellent choice for hot summer days, camping with a gas burner, vacation rentals, or any time you want a homemade meal without heating the entire kitchen. I also like that the batter is neutral enough to work with almost any savory filling, making it a recipe you'll come back to again and again.

   The egg salad sandwich likely originated in late 19th–early 20th century Europe and the U.S., when chopped boiled eggs mixed with mayonnaise became popular. It spread quickly as a cheap, protein-rich lunch, especially in American delis and lunchboxes. Your version with tomato, chives, and parsley is a fresh modern twist.
