These breakfast bars are sweet, crunchy, and incredibly satisfying.
Preheat the oven to 375°F, and line an 8x8-inch) baking pan with parchment paper. Set aside. (Use a large piece that will cover the sides and cut slits in each corner so that it will lay flat.)
Add the oats, almond meal, shredded coconut and salt into a large mixing bowl. Drizzle with the coconut oil, mix until everything is evenly coated, and then pour the mixture onto a baking sheet and roast in the preheated 375°F oven until it's golden brown, about 20 minutes. (Do not wash the bowl you mixed in -- set it aside for later.)
To pop amaranth:
Heat a dry, large, deep skillet -- that has a lid -- over high heat until extremely hot. Carefully add about 1 teaspoon of amaranth grains, cover the pot, and allow them to pop while shaking side-to-side constantly. If they don't start popping within about 5-10 seconds, the pan isn't hot enough.
As soon as the popping slows, quickly and carefully pour into a large bowl. The goal is to get as many to pop as possible, but not to let them burn - if there are some unpopped ones, that's okay. Repeat the process, 1 teaspoon at a time, until all the amaranth is popped.
