💡 Chef Tips
Cut into squares: Pre-cutting the lasagna slice into smaller squares makes it much easier for children aged 4-8 to eat with a fork.
Cold stability: Lasagna holds its layers together very well when cold, making it a great zero-stress lunch option.
Apple browning prevention: Toss apple slices with a tiny splash of lemon juice to keep them fresh overnight.
