Preheat the grill to medium-high.

Thread the chopped salmon and lemon slices through metal skewers (note: you can also use wooden skewers - just be sure to soak them for at least 15 minutes in water before using them).

Generously coat the skewers with avocado oil using a kitchen brush. Sprinkle with sea salt, black pepper, and/or any seasonings you like.

Place skewers on the preheated grill and grill until golden-brown grill marks appear, about 2 minutes. Carefully flip using tongs and grill another 2 minutes. Flip again and continue grilling until salmon is opaque and cooked through (this should take 5 to 8 minutes total).

Serve salmon skewers with cooked quinoa, cherry tomatoes, and a drizzle of pesto sauce.
