Wash and dry produce.
Quarter cucumber lengthwise; slice into ½-inch-thick pieces. Halve tomatoes. Pick and roughly chop fronds from dill. Halve lemon. Halve pitas.
In a medium bowl, toss together cucumber, tomatoes, pepitas, half the dill, a large drizzle of olive oil, and a squeeze of lemon juice to taste. Season generously with salt and pepper.
In a small bowl, combine sour cream, remaining dill, and a squeeze of lemon juice to taste. Season with salt and pepper.
Wrap pitas in damp paper towels and place on a plate. Microwave until warm, 20 seconds. Fill pitas with a bit of hummus, half the roasted red pepper spread (all for 4 servings), veggie salad, dill sauce, feta, and hot sauce to taste. Serve.
