Preheat the oven to 425°F.
Wash and trim the asparagus, then toss with olive oil, salt, and pepper.
Arrange the asparagus on a baking sheet and roast in the oven for about 12-15 minutes until tender and slightly crispy.
Meanwhile, peel and devein the shrimp if not pre-prepared. Pat dry.
In a bowl, combine minced garlic, lemon juice, lemon zest, a pinch of red pepper flakes (if using), salt, and pepper.
Add the shrimp to the bowl and toss until well coated.
Heat a non-stick skillet over medium-high heat. Sauté the shrimp for 2-3 minutes per side until they turn pink and are just cooked through.
Prepare the quinoa as per package instructions if not already cooked, using about 1/2 cup cooked quinoa per serving.
Plate the quinoa as a base, top with lemon garlic shrimp, and add the crispy roasted asparagus on the side.
Finish with an extra squeeze of lemon if desired and serve immediately.
