I have ingredients which will make spinnach and cheese triangles, but there are sooo many recipes online and none have the same ingredients I have for a full recipe. So I will just make one up

I have spinnach, cottage cheese, tasty cheese, onions, eggs, puff pastry. So I will make something with that I think!

Just got me wondering how do you make spinnach and cheese triangles? Any hot tips for a delicious difference?
