Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce.

Cut potatoes into ½-inch-thick wedges. Toss on a baking sheet with a large drizzle of oil, half the Fry Seasoning (all for 4 servings), salt, and pepper.

Roast on top rack until browned and tender, 20-25 minutes.

Meanwhile, quarter lemon. Drain and rinse chickpeas; pat dry with paper towels. Trim and thinly slice scallions. Pick dill fronds from stems; finely chop fronds.

In a small bowl, combine mayonnaise, sour cream, mustard, miso sauce concentrate, garlic powder, ¼ tsp sugar (½ tsp for 4 servings), and a squeeze of lemon juice. Season with salt and pepper.

Place chickpeas in a medium bowl and mash with a potato masher or fork until about half the chickpeas are smooth (leave some larger pieces for texture-packed bites!).

Stir in scallions, half the mayonnaise mixture, as much dill as you like, and lemon juice to taste. Season with salt and pepper.

Melt 1 TBSP butter in a large pan over medium heat. Add sourdough slices; toast until golden brown, 2-3 minutes per side. (Work in batches if necessary, adding more butter for each batch.)

In a second medium bowl (large bowl for 4 servings), toss spinach with a drizzle of olive oil, a squeeze of lemon juice, salt, and pepper.

Spread half the sourdough slices with remaining mayonnaise mixture.

Top remaining sourdough slices with chickpea salad and as much spinach as you like. Close sandwiches and halve on a diagonal.

Divide sandwiches, potato wedges, and any remaining spinach between plates. Serve.
