Preheat oven to 425F convection or 450F if you don’t have convection. Line a baking sheet with parchment paper.
On the baking sheet, add the sweet potatoes, 2 tablespoons oil, and ½ teaspoon salt. Toss to coat, spread into an even layer, and bake for 20-25 minutes, or until they are browned and cooked through (this will depend on how thick/what shape you cut them).
Toss green beans in remaining 1 tablespoon oil and ¼ teaspoon salt, scatter them over the sweet potatoes, and bake for 5 more minutes or until the green beans have softened but are still crunchy.
In a jar with a lid or a small bowl add the tahini, lime, water, soy sauce, and salt and shake or whisk to combine. The sauce should drizzle easily. If it seems too thick, add a splash of water to thin it out. Always taste and add more salt or lime if needed.
You can serve the salad directly on the sheet pan, on a large serving platter, or on each individual plate. However you choose to do it, nestle the eggs into the veggies (if using) and drizzle the dressing generously all over. Top with nuts, herbs, and pickled onions (if using). Sprinkle some kosher or flaky salt and black pepper all over.
Once your salad is on your plate and ready to eat, drizzle more sauce over top (trust me!).
