In a small bowl whisk together the garlic, shallot, lime juice, soy sauce, honey and 1 tablespoon of olive oil. Season the salmon fillets with salt and pepper place in a zip top plastic bag and add half of marinade. Seal bag, removing as much air as possible and let the salmon sit for 30-60 minutes. Reserve remaining marinade.
Toss the broccolini with remaining olive oil on small baking sheet and transfer to the oven. Broil until lightly charred, about 5 minutes. Remove salmon from marinade and nestle on top of the broccolini. Spoon 1/2 of the remaining marinade over and place back under the broiler until the salmon is charred around edges, about 6 minutes.
Spoon the rest of the marinade over the top and add the sliced scallions and sliced Fresno chile. Broil, about 2 minutes more until the salmon is charred and medium at thickest part. Let rest for a few minutes for any residual cooking and serve.
