Unfortunately, I too am from a region that does not really value lentils. We have a singular lentil dish that's really popular here, but hardly anything beyond that.

The dish also hardly uses seasoning. 🫠
Very basically, you cook some brown lentils and separately, make a roux. Then combine the two. Add salt, a bayleaf and a splash of vinegar. Eat with soft noodles.

As for non-regional recipes that I'm aware of:

• Lentil curry is great. You can basically just make a normal curry and replace whatever protein you'd use with lentils.
• The Indian cuisine has tons of dishes under the term "dal". I believe, that word does just mean "split lentils", but you will find lots of recipes with that term anyways.
  To my knowledge, what many(/most?) of these recipes also share is that they overcook split lentils until they disintegrate and you're left with a creamy base, which you can then pimp with all kinds of spices.
