The asparagus took longer to cook than the salmon. I suggest that you do this first. I roasted them directly in the oven at 400 degrees for 20 minutes. The veggie was coated with olive oil, salt, pepper, thyme, garlic powder and my secret ingredient - a dash of turmeric. It's a spice that's commonly used in Indian cooking. It gives a slight smokey taste, much milder than cumin does and I love it in my roasted vegetables.
This dish is so easy and delicious. It is just the right one to do when you are hungry but too tired to spend time in the kitchen. Try it.
