Bring a medium pot of salted water to a boil and cook the chickpea pasta according to package instructions until al dente.
While the pasta cooks, pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the skillet skin-side down (if applicable) and sear for 4-5 minutes until the skin is golden and crispy.
Flip the salmon and cook for an additional 2-3 minutes until cooked through to your preference, then remove from the pan and set aside.
In the same skillet, add the minced garlic and baby spinach, sautéing for 1 minute until the spinach is just wilted.
Drain the pasta, reserving a splash of pasta water, and return the pasta to the pot.
Stir in the basil pesto, lemon juice, sautéed spinach, and garlic, adding a touch of pasta water if needed to thin the sauce.
Plate the pesto pasta and top with the golden salmon fillet, finishing with an extra squeeze of lemon if desired.
