Combine garlic, sumac, red pepper flakes, coriander, cumin, and 1 tsp. salt in a small bowl. Arrange tomato slices in a single layer on a rimmed baking sheet and sprinkle garlic mixture evenly over top. Let sit at room temperature at least 30 minutes and up to 1 hour.
Toss chickpeas and vinegar in a medium bowl; season with salt and pepper. Mash chickpeas with a fork until about half are smashed. Add shallot, parsley, and oil and toss to combine; season with salt and pepper. Set aside.
Top each flatbread with yogurt sauce, chickpea mixture, and tomatoes. Drizzle with more oil and season well with salt and pepper.
Make the marinade: In a medium bowl, whisk the tahini, soy sauce powder, sesame oil, sugar, rice wine vinegar powder, ginger powder, pepper, Sriracha powder and water until smooth. Set aside 2 tablespoons of the sauce and refrigerate. Add the shrimp to the remaining marinade and refrigerate for 30 minutes or up to 4 hours.
Grill the shrimp: Prepare a charcoal or gas grill for medium-hot cooking or place a grill pan over medium-high heat. Brush the grates or grill pan with 1 teaspoon of the canola oil. Remove the shrimp from the marinade, letting the excess drip off, and season with the kosher salt. Grill the shrimp in 2 batches, flipping once, until charred and cooked through, 1½ to 2 minutes on each side. Transfer to a plate and chill.
Wipe the grill clean and prepare for medium-hot cooking. Season the mango and tomato with salt and pepper, and grill, turning once, until charred, 3 to 5 minutes. Set aside and chill.
Bring a medium pot of water to a boil, add the soba noodles and cook until al dente, 3 to 4 minutes. Drain and rinse the noodles under cold water to stop them from cooking. Transfer them to a paper-towel lined baking sheet to dry.
Remove the mango and tomato from the fridge and roughly chop. Set aside.
Taste and adjust the seasoning of the reserved marinade, thinning it out with water as needed. In a large bowl, toss the marinade and noodles to coat evenly. Add the shrimp, mango, tomato, half of the scallions, basil and half of the sesame seeds. Divide the noodles among 4 to 6 plates and top each with some of the remaining scallions and sesame seeds, and serve.
Heat the olive oil in a large frying pan over medium heat and add harissa, tomato paste, peppers, garlic, cumin, and 3/4 teaspoon salt. Stir and cook over medium heat for about 8 minutes to allow the peppers to soften. Add the tomatoes, bring to a gentle simmer, and cook for a further 10 minutes until you have quite a thick sauce. Taste for seasoning.
Make 8 little dips in the sauce. Gently break the eggs and carefully pour each into its own dip. Do the same with the yolks. Use a fork to swirl the egg whites a little bit with the sauce, taking care not to break the yolks. Simmer gently for 8 to 10 minutes, until the egg whites are set but the yolks are still runny (you can cover the pan with a lid if you wish to hasten the process). Remove from the heat, leave for a couple of minutes to settle, then spoon into individual plates and serve with the yogurt.
