Preheat the oven to 350F. Line a baking sheet with parchment paper.
In a medium pot over high heat, add the farro and enough water to cover by at least 2-inches. Bring to a boil, then reduce heat to low and simmer until cooked through, about 20-30 minutes. Drain and set aside.
Add your mix of seeds to the baking sheet along with the olive oil, spices, and salt. Toss to thoroughly coat. Bake for 10 minutes, stirring halfway through. Transfer to a plate to cool.
Increase the oven to 450F or 425F convection. Line the same baking sheet with parchment paper.
Add carrots, broccoli, and bell pepper to the baking sheet and toss with the oil and ½ teaspoon salt. Bake for 15 minutes, or until the broccoli gets deeply charred (like kind of burnt!).
Meanwhile, in a large bowl, combine the fennel, lemon and remaining ¼ teaspoon salt. Set aside.
Finally, let’s make the sauce! Add all of the ingredients to a high speed blender and blend until smooth. Depending on the thickness of your tahini, you will need to add more or less water, so be sure to taste and add more salt or lemon, if needed. If the sauce is too runny, you can add more tahini. Keep in mind that it will thicken up in the fridge.
Add the warm farro and roasted veggies, fennel slaw, and halved boiled egg to your bowl. Sprinkle some salt on that egg. Top generously with the sauce, spiced seeds, more fresh herbs, black pepper, and a generous squeeze of lemon.
