Make the salmon paste
Cut about two-thirds of the salmon into chunks and place in a food processor.
Pulse for 15-20 seconds until a thick, sticky paste forms.
Transfer the paste to a large bowl.
Chop the remaining salmon
Dice the remaining one-third of salmon into small pieces, about 1/4 inch.
Add the chopped salmon to the bowl with the paste.
Mix the ingredients
Add almond flour, jalapeño, cilantro, green onions, garlic, lime zest, salt, and pepper to the bowl.
Using your hands, gently squeeze and fold the mixture until evenly combined. Don't overwork it.
Form the patties
Divide the mixture into 6 equal portions.
Shape each portion into a patty about 3/4 inch thick.
Press gently to compact the patties.
Cook the burgers
For grilling: Preheat grill to medium-high heat. Oil the grates. Cook patties for 2-3 minutes per side until internal temperature reaches 135°F.
For stovetop: Heat butter or olive oil in a skillet over medium-high heat. Cook patties for 2-3 minutes per side until golden brown.
Rest and serve
Remove burgers from heat and let rest for a few minutes.
Top with guacamole or avocado slices. Serve immediately.
