Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Halve the baby potatoes and toss them with half of the olive oil and a pinch of sea salt.
Roast the potatoes for 20 minutes or until they are golden brown and tender when pierced with a fork.
While potatoes roast, season the chicken breast on both sides with sea salt, black pepper, and dried oregano.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 6 to 7 minutes per side until fully cooked.
Add the asparagus to the skillet during the final 5 minutes of chicken cooking, turning occasionally until bright green and tender.
Mince the garlic and whisk it together with the lemon juice and lemon zest in a small bowl.
Pour the lemon-garlic mixture over the chicken in the pan, allowing it to bubble and glaze the meat for 1 minute.
Plate the chicken alongside the roasted potatoes and asparagus, drizzling any remaining pan juices over the top.
