Bring 2 liters of water to a boil. Add dried lentils, salt, smashed scallion, garlic and a sprig of thyme. Allow this to simmer on low for 40-60 minutes. Drain all the water from the lentils in a colander, remove herbs and set them aside in a large bowl.
In a skillet over high heat, add oil, diced onion, shredded carrot, minced garlic, dried parsley, maple syrup, salt and liquid aminos and stir continuously. Once the onion and garlic become fragrant, reduce heat to medium and allow this to sauté for 5 minutes, stirring occasionally. Remove from heat and add to the drained lentils.
Blend rolled Oats dry leaving just a few grains in-tact, the rest should look flour-like. Add to the lentil mixture.
Add wheat gluten and browning and mix well. Set aside in the refrigerator for one hour or overnight.
Preheat oven to 350ºF (175ºC) and grease a sheet pan.
To make sauce add all ingredients to a small bowl and mix well.
Remove the lentil mixture from the refrigerator and spread it evenly in your sheet pan to about a ¼ inch thick.
Brush a generous amount of the sauce on top until evenly distributed. Do not forget to reserve some for when you remove it from the oven.
Using a knife, cut the lentil mixture into squares to make them easy to remove when they are done baking.
Bake your lentils in the oven for 15-20 minutes. Remove and brush on remaining sauce.
Serve immediately with your side of choice. Enjoy!
