Hachis parmentier

A simple winter basic, cheap, easy to cook in large quantities. You can freeze some of it and reheat it in the oven later.

Hachis parmentier
6 large potatoes
2 tbsp butter or vegetal sustitute
1 cup oat milk
11 oz ground beef
11 oz ground pork
 2 large onions
thyme, laurel, rosemary
salt, pepper to taste
optional : 1 cup grated cheese

Peel and dice the potatoes, cook them in a pressure cooker until you can squash them with a fork.
Peel and thinly slice the onions. In a pan, heat one dash of oil over strong heat, put the onion and stir them regularly until they get a little transparent. Add the meat, separated in little clumps, salt, pepper, and herbs. Stir and sauté  the onion and meat mix until the meat is nicely golden.
Squash the potatoes, adding the butter and milk as you go (you can also use one small cup of almond or rice cream instead of the butter + milk).
In a large oven-proof pan, spread the meat mix first, and the mashed potatoes on top of it. Add some cheese on top if you wish/can. Cook in the oven at 250°F until the top is lightly golden.

It's one of those dishes that reheats well, so don't hesitate to cook it in advance and just reheat it for dinner.
