Preheat the oven to 425°. Lay 4 large sheets of parchment paper on a work surface. Divide the Broccolini among the sheets and top each mound with a salmon fillet, 2 lemon slices and a few chile rings; drizzle each with 1 1/2 tablespoons of olive oil and season with salt and pepper. Fold the parchment over the fish, then fold the edge over itself in small pleats to seal the papillotes.
Transfer the papillotes to a large baking sheet and bake for 15 minutes, until slightly puffed. Carefully snip the packets open with scissors and serve.
