Step 1

Preheat oven to 400F.

Step 2

In a medium bowl, place the two pieces of salmon. Pour 1 tbsp olive oil and sprinkle salt, pepper, and dried oregano.

Step 3

Cut two sheets of foil. It has to be big enough to wrap the salmon and asparagus.

Step 4

First place asparagus (about 8 spears) on the sheet of foil.

Step 5

Layer fillets over asparagus.

Step 6

Then top each with about 2 onion slices and 2 lemon slices.

Step 7

Wrap sides of foil inward over salmon then fold on top and bottom of foil to enclose.

Step 8

Place foil packets in a single layer on a baking sheet.

Step 9

Bake in preheated oven for about 12-15 minutes. (The time will depend on the thickness of your salmon and the power of your oven.)

Step 10

Unwrap and using a large spatula, transfer the foil packets to plates. Serve warm.
