How to Make It
Preheat oven to 350°F.
Combine oats and 1/4 cup water in a large bowl.
Combine oil, sugar, and eggs in a small bowl, beating well with a whisk. Add egg mixture to oat mixture, tossing to combine.
Weigh or lightly spoon flour into a dry measuring cup; level with a knife. Combine flour, nuts, flaxseed, thyme, salt, baking soda, pepper, and cheese. Add flour mixture to oat mixture; toss with a fork until a sticky dough forms. With floured hands, knead dough 2 to 3 times. Divide dough into 12 equal portions, and shape each portion into a 1/4-inch-thick triangle. Place triangles on a baking sheet lined with parchment paper. Bake at 350°F for 16 to 18 minutes or until golden.
