Halloween lentil mummy ingredients switch help request: meat for lentils?

Happy halloweenie!

I was looking for something cute to make tomorrow, and I came across this recipe – https://www.yourhomemadehealthy.com/mummy-meatloaf/#recipe

However I want to make the meatloaf out of lentils or something similar. Do any of you have a recipe for a lentil loaf that might work?

I'm open to other suggestions too!

Tyvm!
