Roll out the untoasted toast on a work surface with a rolling pin. Brush a muffin tin with butter and carefully press in the toast. Mix the tuna with the cottage cheese and stir with salt, pepper and a little chili. Pour approx. 1 tablespoon of it into each of the toast molds and top with an egg. Season again with a little salt and if you want, you can sprinkle a little chives or spring onions over it. Place in the oven at 180 ° C for about 20 minutes, until the egg has set.
Instead of tuna and cottage cheese, you can also use salami, ham, salmon, tomatoes or just the egg.
