Steelcut oats take a while to cook stovetop. This mason jar method is a great timesaver and results in a consistency like soaked muesli. We topped ours with blueberries and peaches, but you could use raspberries and apples or any other combination that suits your fancy.
Place oats and chia in 1 litre mason jar; screw metal lid on and shake to combine.
Bring almond beverage, maple syrup, salt and 1 cup (250 mL) water to a boil in small saucepan; immediately pour over oat mixture. Screw lid on tightly to close. Holding jar in tea towel, shake gently to combine. Let stand on counter 10 minutes, shaking once or twice. Refrigerate for 12 hours. (Make-ahead: store in refrigerator for up to 3 days.)
Scoop oats into four bowls. Top each with an equal amount of walnuts and fruit.
