Add flax to water in a small bowl and let it sit for a couple of minutes.
Drain and rinse the black beans and add them to a mixing bowl.
Mash the beans with a fork to your desired preference- I like them mostly mashed with a few whole beans left over.
Add the prepared couscous, diced onion, flax, and spices to the beans and combine well.
Test for taste and adjust to your preferences.
Combine the flour and cornstarch on a plate.
Heat a nonstick pan over medium to medium-high heat.
Divide the bean mixture into 4, then form the patties by compacting them into a ball and flattening making sure to go around the edges with your thumb the ensure the edges are compacted.
Place the patty in the flour mixture to lightly coat the patty on both sides. Reform a bit if needed.
Lightly spray pan with cooking spray just before adding the patties to the pan.
Let the patty cook about 8 minutes.
Check the bottom for doneness.
Lightly respray the pan when you flip the patty so it crisps a bit and removes easily.
Cook for another 8 minutes.
Once burgers are done, serve on a bun with your favorite burger toppings with my burger sauce.
To make the sauce combine all ingredients and mix until smooth.
Adjust ingredient amounts based on texture and flavor preferences.
