Press the extra firm tofu between paper towels for 10 minutes to remove excess moisture, then slice into thick strips.
Preheat your oven to 400°F and toss the broccoli florets and red bell pepper with a light mist of oil and a pinch of salt.
Roast the vegetables for 15-20 minutes until the edges are tender and slightly browned.
Heat a non-stick grill pan over medium-high heat and sear the tofu strips for 3-4 minutes per side until golden char marks appear.
Bring a small pot of water to a boil, carefully lower in the egg, and cook for 6 and a half minutes for a jammy yolk, then peel and halve.
In a small bowl, whisk together the tahini, lemon juice, nutritional yeast, and a tablespoon of warm water until smooth.
Assemble the bowl by placing the cooked quinoa at the base, topped with the roasted vegetables, grilled tofu, and the egg.
Drizzle the creamy lemon tahini sauce over the entire bowl and enjoy immediately.
