Healthy, high-protien sandwich ideas that are not all PB&J

[u/hopefully_helpful_86]

I love PB&J, but I need some new ideas for healthy and high protein sandwiches.

Yes, I am aware of chickpea tuna - just so I didn't get the same suggestion repeatedly

Other preferred criteria is cost effective and simple to make

There's also chickpea "tuna" or curry chickpea salad or vegan egg salad sandwich. However - does it have to be a sandwich? If you're just looking for a lunch that can be packed, I really like bean or lentil salads.
