Rinse quinoa and cook according to package directions. Fluff with a fork and set aside to cool.
Place potatoes in a pot of salted water. Bring to a boil and cook until fork-tender, about 12–15 minutes. Remove potatoes and halve. (Keep water boiling for green beans)
Blanch the green beans. Add beans to boiling salted water for 2–3 minutes until crisp-tender. Transfer to an ice bath to stop cooking. Keep water boiling for eggs
Place Greens Beans and Halved Potatoes on a sheet pan, drizzle with olive oil and season with salt, ½ teaspoon thyme, and ½ teaspoon oregano. Broil on high in oven for about 4 minutes or until slightly crispy.
Cook the eggs. Gently lower in eggs and cook for 7 minutes for jammy yolks. Transfer to ice bath, peel, and slice in half.
Sear the salmon. Season salmon with salt and pepper. Heat a drizzle of olive oil in a skillet over medium-high heat. Cook salmon 3–4 minutes per side, until golden and flaky. Remove skin if desired and flake or slice.
Make the vinaigrette. Whisk champagne vinegar, Dijon, honey, and shallot. Slowly stream in olive oil while whisking until emulsified. Stir in ¼ teaspoon oregano and ¼ teaspoon thyme.
Assemble the salad. In 2 separate bowls, arrange ½ cup cooked quinoa, 2-3 sliced potatoes, green beans, radishes, avocado, 1 egg (peeled and halved), a salmon filet, and capers. Drizzle with vinaigrette and serve immediately.
