First, rinse the dry lentils, drain them, and add them to a medium sized saucepan over medium heat.
To the saucepan, add the canned tomatoes, crushed garlic, pinch of salt, water, and chipotle paste (or powder). Cook with the lentils for about 10 minutes.
Now would be a good time to preheat your oven to 350 degrees F. Next, add the chopped up broccoli, cumin, paprika, cayenne pepper, and onion powder to the saucepan and cook with the lentil mixture for another 10 minutes or until most of the liquid has evaporated. The mixture should be somewhat dry in order to patties that stick together.
Allow the lentil mixture to cool down for 2-3 minutes, and then add the lentil mixture and pinto beans to a medium to large sized bowl. Add the squeeze of lemon juice if adding and mix everything together. If you have a potato masher, you can use it to mash the mixture together, but I used a large spoon and it worked finer for me. Try to get all or most of the black beans mashed so that they can act as a glue to hold the patty together.
Next, mix in the bread crumbs into the mixture until it is evenly spread out throughout the mixture. Scoop the lentil and bean mixture into a plate, and press down on the mixture so it forms one even layer on top of the plate. Put the plate in your freezer for 10 minutes to allow the mixture to become more coherent. Once you take the mixture out of the freezer, the patties are ready to shape!
You can use a cookie-cuter or glass to cut out the circular patties from the plate, but I chose to shape them with my hands and it turned out fine (just a tad bit more messy). If you want larger patties to serve fewer people, form 5 patties, and if you want smaller patties to serve more people, then form 6 patties (each will have about 190 calories).
Finally, place the patties on a sheet-pan and bake them in your preheated oven for 20 minutes. Remove the patties from the oven, flip them over, and cook them for another 15 minutes.
Allow your patties to rest for 3 minutes, then serve and enjoy! These patties are sooo good with avocado and hot sauce :)
