Thoroughly wash quinoa using a sieve, and shake to drain.
Tip quinoa into a medium-sized pan and set aside.
Boil water and then tip over quinoa, add salt, and place on high heat.
Once water begins to boil, lower to a simmer and cover.
Cook until the water has fully absorbed (approx. 15 mins).
While quinoa is cooking, wash and trim asparagus and sauté in a pan with a little oil.
Do not overcook the asparagus, your stems should retain its deep green color and should still snap when you break them.
Cut tomatoes in half lengthwise.
Drizzle asparagus and tomatoes with a little olive oil and salt and pepper and set aside.
Once quinoa is cooked fork through quinoa to separate and then mix with parmesan.
