Can I interest you in a super cheesy and delicious lasagna thermos lunch?
You read that right, today I am sharing how to pack everyone’s favorite pasta recipe, so everything stays hot until lunchtime! Sounds good to you? Let’s get started.

Easiest Lasagna Ever
This no-bake lasagna is the easiest recipe partly because it’s made with simple ingredients but mostly because there’s no baking or a ton of layering involved.
Instead, you will assemble the cooked ingredients directly into your bowl (for dinner) or thermos (for lunch). It goes a little like this- sauce, lasagna noodles, cheese, more lasagna noodles, more sauce, and more cheese.
How easy is that, and you get all the classic lasagna flavors in a fraction of the time! Who doesn’t love the sound and taste of that?
