What are your go-to pantry-friendly weeknight dinners with leftovers?

[Paisley65]

I'm in a major weeknight dinner rut, cycling through the same three pasta and stir-fry recipes because they're fast, but my family is getting bored. I need ideas for meals that are genuinely quick to prepare from start to finish, use mostly pantry staples or easy-to-find fresh ingredients, and ideally make decent leftovers for lunch. For other busy home cooks, what are your go-to recipes that feel like a real meal but don't require a ton of prep or specialized ingredients, and how do you organize your week to avoid the last-minute scramble?
