A hearty budget-friendly casserole featuring protein-rich tuna (or chickpea pasta for extra plant-based protein) perfect for family dinners and made mostly from pantry staples.

This recipe first came together on a busy weeknight when I wanted something everyone would eat without complaints. The crispy topping and flavorful sauce make it a family favorite, especially when I switch out the protein for chickpeas when needed.
