Cut 4 pieces of parchment paper and lightly grease them with olive oil.
Divide the asparagus over the 4 pieces of parchment paper.
Spoon the tomato salad on top of the asparagus.
Place one salmon fillet on each pile of vegetables.
4 pieces salmon fillet
Crumble 1 tablespoon of feta over each piece of salmon.
4 tablespoons feta cheese
Fold the parchment tightly into parcels and tie with twine.
Place the parcels in the oven and bake for about 25 minutes, until the salmon is cooked.
Open carefully and serve immediately.
NOTES
1. Can I use aluminum foil instead of parchment?You can. Foil parcels work the same way; just make sure they are sealed well.2. How do I know the salmon is done?It should flake easily with a fork and change from translucent to opaque in the center.3. Variations
Herb swap: Use rosemary or basil instead of thyme, as suggested in the post.
Different fish: Replace salmon with cod or another firm white fish, like cod, tilapia or pangasius.
4. StorageBest served fresh. If you have leftover salmon and vegetables, cool them quickly.
Fridge: Store in a closed container for up to 1 day.
Freezer: Not recommended for the finished parcels; the vegetables and fish lose texture.
Reheat/Serve: Reheat leftover salmon gently in the oven or microwave with a splash of water, just until warm.
