Soak chia seeds: In a medium bowl, whisk together the chia seeds, soy milk, and yogurt until well combined. Let it sit for 15 to 20 minutes (or refrigerate overnight) to thicken into a creamy base. Stir once or twice to prevent clumping.
Prepare the cucumber, bell peppers, pumpkin seeds, and parsley. Mash the cooked chickpeas.
Combine: Stir the chickpeas, grated cucumber, chopped roasted peppers, chopped pumpkin seeds, lemon juice, zest, and parsley. Grate the garlic into the mixture. Mix well to combine.
Season with salt, pepper, and more lemon juice to taste.
