Soak the lentils for half an hour or more in warm hot water.
Wash, drain, add to a pot with all the ingredients (salt, garlic, spice, 1 3/4 cups water) and cook on low-medium, partially covered for half an hour or until easily squished. Stir a few times in between. Cook until all the water is absorbed. (drain the lentils if they are well cooked and water is not absorbed). Or use 1.5 cups of cooked lentils.
Grate the cauliflower (in a food processor, blender or by hand), spread on a parchment lined baking sheet and bake at pre-heated 400 degrees F for 12-15 minutes until some of the cauliflower gets crisp and golden. (You can also dry roast the grated cauliflower on stove top in a large pan at medium heat for 5-6 minutes).
Add cooked red lentils, roasted cauliflower, spices, salt to a bowl and mix well. Mash a bit. Taste and adjust salt and spice. (You can use this mixture as is to load a burger or a taco too.)
Add chickpea flour, mix until the lentil cauliflower mixture easily comes together. Add more flour or breadcrumbs if needed (depends on moisture content in the lentils, cauliflower, etc). Shape into burger patties by hand or by pushing through a 3 inch cookie cutter.
Drizzle with olive oil, if using. Bake on parchment lined sheet for 20 minutes at 400 degrees F.
Assemble the Burger: Top the bun with spinach/greens, some mayo, onion rings, warm lentil patties, roasted peppers, pickled jalapenos, more chipotle habanero mayo, fresh cilantro and bun.Or use your own toppings like cucumbers, raw red onion slices, pepper slices and such for a quicker fix up.
Onion Rings
Mix 3 Tablespoons chickpea flour, 1/4 cup water, 1 teaspoon oil, salt, garlic powder into a paste. Add a teaspoon rice flour for crunchyness. (optional)Dip red onion slice in the the batter and place on parchment lined sheet.Bake for 15 or so minutes at 400 degrees F. You can bake them when baking the cauliflower or the patties.
Roasted Mini Peppers
Chop up the mini peppers or red pepper, and bake with the onion rings or patties for 15-20 minutes. You can toss them in oil if you want. I did not use any.
Chipotle Habanero Mayo
Mix 1 Tablespoon Chipotle habanero (I used Melinda's Chipotle Habanero) sauce or chipotle sauce or hot sauce with 4 Tablespoons vegenaise or homemade mayo or cashew cream or coconut cream.
