Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Trim the woody ends off the asparagus and place them on the baking sheet with the cherry tomatoes.
Drizzle the vegetables with half of the olive oil and season with half of the sea salt and black pepper.
Roast the vegetables in the oven for 12 to 15 minutes until the asparagus is tender and tomatoes are slightly blistered.
While the vegetables roast, season the chicken breast on both sides with the dried oregano and the remaining salt and pepper.
Heat the remaining olive oil in a skillet over medium-high heat.
Place the chicken in the hot skillet and sear for 5 to 7 minutes per side until the internal temperature reaches 165°F.
Lower the heat to medium-low and add the ghee, minced garlic, lemon juice, and lemon zest to the pan.
Spoon the bubbling lemon-garlic sauce over the chicken for 1 minute until the chicken is beautifully glazed and fragrant.
Serve the chicken immediately alongside the roasted vegetables, pouring any remaining pan sauce over the top.
