4-5oz salmon fillets (I usually I just do 2 6-8 oz fillets)
2 T Dijon mustard
2 T lemon juice
1 T olive oil
1 T fresh minced thyme
1 T fresh minced rosemary
1 tsp dried oregano
1/2 tsp salt
1/2 tsp pepper
1 small yellow onion, thinly sliced
2 tomatoes, thinly sliced
Make 3 to 4 1/4 inch deep slits along the top of each salmon fillet.
Combine mustard, lemon, oil, herbs, salt and pepper.
Coat the salmon on both sides.
Cover and refrigerate for 30-60 minutes.
Heat oven to 450 degrees.
Arrange tomato and onion slices in the bottom of a glass baking dish.
Microwave for 3-5 minutes (just cooks the onions a little).
Place salmon on top of onions and tomatoes.
Roast for 10-15 minutes, according to desired doneness.
Enjoy it all together!
