Season the chicken breast evenly on both sides with sea salt, black pepper, and dried oregano.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Place the chicken in the skillet and grill for 6-7 minutes per side until the internal temperature reaches 165°F and the outside is golden brown.
Remove the chicken from the heat, let it rest for 3 minutes, then slice into thin strips.
Prepare the vegetables by dicing the cucumber, halving the cherry tomatoes, and finely mincing the red onion.
In a shallow serving bowl, add the cooked quinoa as the base layer.
Arrange the sliced chicken, cucumber, cherry tomatoes, red onion, and kalamata olives in sections over the quinoa.
Add a dollop of the roasted red pepper hummus to the center of the bowl.
Drizzle the fresh lemon juice over the entire bowl just before serving to brighten all the flavors.
