How to cook a brisket
Saute the sliced onions.
Place a skillet on the stove and pour in 1 tablespoon (15 ml) of olive oil. Turn the heat to medium and thinly slice 1 1/2 pounds (680 g) of yellow or red onions (about 2 large onions).
When the skillet is hot, add the onions. Stir the onions occasionally and cook them for about 20 minutes.
