What is your way of making keto lasagna?

Let's consider a classic ragu Bolognese style lasagna. The meat sauce is keto friendly (unless we use too much tomato product or onion, but that is under our control). A white sauce (e.g., cottage cheese, or ricotta based) is fine as well. The main problem is finding a replacement for the pasta sheets.

There are several options for keto lasagna sheets:

1. Deli meat sheets
2. Cabbage leaves
3. Eggplant slices cut lengthwise
4. Zucchini slices cut lengthwise
5. Storebought keto tortillas
6. Storebought egg white wraps
7. Something else?
