Season the chicken well before searing for best flavor.
Season the chicken: pat dry, toss with olive oil, garlic powder, oregano, paprika, salt, pepper, and lemon zest.
Sear the chicken in a hot skillet 3–4 minutes per side until golden; set aside with juices.
Toast the rice: melt butter, add garlic 30 seconds, stir in rinsed rice 1–2 minutes.
Add broth and lemon juice, scrape up browned bits, stir in oregano and salt, bring to a gentle boil.
Nestle chicken back on top, cover, simmer on low 12 minutes without peeking.
Rest 5 minutes off heat, scatter peas, fluff with a fork, finish with parsley and lemon wedges.
