Instructions
Onion: Heat oil in a large pot over medium heat. Add diced onion and cook until translucent and soft, about 3 minutes.
Veggies: Add mushrooms, carrots, and garlic. Continue cooking until mushrooms release their moisture, about 8 to 10 minutes.
Fillings: Stir in oats, lentils, and broth. Cover and cook until oats are al dente (they should be mostly cooked, but have a little bite to them). This should take 20 to 30 minutes.
Prep For Baking: While oats and lentils cook, preheat oven to 400°F (204°C). Line a bread pan with parchment paper so that bottom and sides are completely covered.
Bake: Pour mixture into your prepared pan, then bake for 30 minutes, or until dry to the touch and a bit darker brown on top.
Serve: Serve from the pan or transfer to a serving plate. The haggis will be thick but will not hold it's shape, so spoon it onto plates and enjoy!
