Cut the Chinese cabbage into very fine, thin strips and fry them together with the diced onions and garlic cloves for 5 - 10 minutes. First only add the white, then the light green. Then stir in the cream cheese and season with plenty of salt and pepper.
Mix the cream and eggs together and season well.
Grease a baking dish. Put in 3 lasagne sheets, then half of the cabbage mixture, three more lasagne sheets and the other half of the cabbage mixture. Finish with 3 lasagne sheets and pour the cream and eggs on top. Then sprinkle the previously roasted sunflower seeds on top. Put everything in the oven at approx. 200 ° C top / bottom heat for 30 - 35 minutes, until the surface is nicely browned.
This is the meatless variant - if you don`t want to make the whole thing meatless, you can fry the minced meat with the cabbage until crumbly or diced ham - depending on your taste! And / or stir a strong cheese into the cabbage mixture!
