Mix the ground flaxseeds and water in a small bowl and set aside.
1 Tablespoon ground flaxseeds, 4 Tablespoons water
Saute the onion in a little water over medium heat until soft and slightly translucent.
½ cup diced onion
Add the garlic and saute for 30 seconds.
3 cloves garlic
Add the celery and carrots and saute for a couple of minutes until softened. Add a splash of water if the pan appears dry.
¼ cup diced celery, ¼ cup diced carrots
Transfer the cooked vegetables to a large mixing bowl. Add the lentils, panko breadcrumbs, 2 Tablespoons ketchup, Dijon mustard, Italian seasoning, flaxseed mixture, and salt and pepper, to taste. Fold together until well combined.
2 15-ounce cans lentils, 1 Tablespoon Italian seasoning, 2 Tablespoons ketchup, 1 Tablespoon Dijon mustard, 1 cup panko breadcrumbs, salt and pepper
Divide the lentil mixture among the cups of a standard 12-cup muffin pan and pat each one down tightly. If using a metal pan, lightly grease the cups to prevent sticking. A nonstick silicone muffin pan does not need to be greased.
In a small bowl, combine the ¼ cup ketchup and balsamic vinegar. Brush the glaze over the tops of the lentil meatloaf muffins.
¼ cup ketchup, 1 teaspoon balsamic vinegar
Bake for 25 to 30 minutes.
Remove the pan from the oven and allow the muffins to rest for 5 to 10 minutes. Carefully remove them from the pan and serve.
