Notes
Vegetables: You can use almost any vegetables you like, including leftover stems from broccoli or cauliflower. You’ll need about 1.7-2 lbs (800-900 g) of various vegetables.
Chili: You can leave it out or replace it with a pinch of cayenne pepper or red pepper flakes to taste.
Lasagna sheets: If your pan is longer than mine, you may need to break one or two extra sheets in half to fill any extra space at the end.
Mozzarella: You can also use mozzarella balls; they are creamier and have a milder flavor.
