Peel the onion and cut it into small cubes. Set it aside in a bowl.
Cook the onion
Heat the oil in the skillet over medium heat. Add the onion and cook for 5 min, stirring, until translucent.
Mash the beans
Drain the canned black beans in a colander. In a bowl, mash them with a fork or potato masher until coarsely chopped.
Tip · If the mixture is too sticky, wet your hands a little with water to make shaping the patties easier.
Mix everything
Add the cooked onion, breadcrumbs, egg, cumin, salt and pepper to the bowl with the beans. Mix well until evenly combined.
Shape the patties
Split the mixture into two equal portions. Shape two thick patties with your hands, making sure they hold together.
Cook the patties
Put the skillet back over medium heat with a little oil. Add the patties and cook 4 min per side, until golden and crispy.
Tip · For the best crunch, press lightly on the patties with a spatula while they cook.
Toast the buns
In the same skillet, toast the two burger buns over low heat for 2 min per side, until lightly golden.
Build the burgers
Slice the tomato and tear the lettuce into pieces. On each toasted bun, place a patty, half of the cheddar, a few lettuce leaves and some tomato slices. Close with the top bun.

Pantry salt, oil and spices aren't counted. Your store and your brands will move the total, but the ballpark is right.
How long does it keep?
Eat it fresh. Bread and wraps get soggy when they sit with the filling. Prep the filling ahead if you want, and put it together the day you eat it!
