There are two different recipes I make. I make the similar keto noodles with this recipe but I replace the kale with roasted radishes. I think the roasted radishes have a creamy taste that is more like a real noodle. The kale keto noodles are awesome but if you eat them alone, you will taste the kale. In a lasagna recipe, you won't even notice a kale taste at all.
Mascarpone has a higher fat content and works wonderfully in this recipe but you can use cream cheese too.
