For Lentil Patties:
For Basil-Arugula Cashew Cream:
To make Lentil Patties: Place lentils in a small pot and add broth. Cover and simmer over medium heat about 45 minutes, stirring occasionally, until very tender. Drain any leftover liquid and transfer cooked lentils to a bowl and stir in chia seeds. Add carrots, potato, onions, arugula, basil, garlic, mustard, oats, bread crumbs, soy sauce, and pepper (if using) to taste. Stir well to make a thick mixture. Place 1 tablespoon olive oil in a large skillet (cast iron works well). Heat well. Form patties by pressing a handful of the lentil mixture into a firm, thick patty. Lay in skillet (four or five per batch) and cook for 7 minutes on medium heat. Turn carefully and cook on the other side for 7 minutes. Repeat the process, adding the rest of the oil to the pan as needed, until all patties are cooked.
To make Basil-Arugula Cashew Cream: Put 1 cup Basic Cashew Cream into a blender. (Note that the recipe for Basic Cashew Cream makes 3 cups, so you can either cut the amount of ingredients you use or make the full recipe and set aside a portion to use later.) Add fresh arugula and basil and process until smooth, creamy, and light green in color.
Serve each Lentil Patty with a dollop of Basil-Arugula Cashew Cream. Refrigerate any leftovers in an airtight container for up to 3 days.
