- 1 blood or Valencia orange, sliced 1/8″ thick, seeds removed
- 1 Meyer or regular lemon, sliced 1/8″ thick, seeds removed
- 4 tablespoons olive oil, divided
- Kosher salt, freshly ground pepper
- 1/4 small red onion, thinly sliced
- 2 tablespoons fresh Meyer or regular lemon juice
- 1 bunch watercress or arugula, thick stems trimmed
- 1/2 cup fresh mint leaves
- 1 avocado, cut into wedges
- Preheat oven to 425°. Toss orange and lemon slices with 1 tablespoon oil on a rimmed baking sheet; season with salt and pepper. Roast citrus, tossing occasionally, until lightly charred in spots and starting to caramelize, 10-15 minutes. This makes the citrus flavor more complex. Let cool.
- Meanwhile, combine onion and lemon juice in a large bowl; season with salt and pepper and let sit 5 minutes (onion will soften a bit and get slightly sweeter and less harsh).
- Add roasted citrus to bowl with onion along with arugula and mint. Drizzle remaining 3 tablespoons oil over; season with salt and pepper and toss everything to combine and coat.
- Add avocado and very gently toss until lightly dressed (you don't want to crush the avocado).
