In a medium bowl, mash together the avocado and lime juice.
Add half of the beans, garlic powder, and salt. Mash together.
Add the chia seeds, jalapeño, green onions, oats, and remaining beans. Stir well to combine completely.
Shape into 4 patties, and refrigerate for at least 15 minutes or up to overnight (make sure to cover them).
When ready to cook, heat oil in a large skillet over medium-high heat. Add in patties, making sure they don't touch. Cook for about 5-7 minutes per side, until crispy on the outside.
Sprinkle with fresh chopped cilantro, and serve with salsa, if desired. Enjoy!
