Preheat oven to 400°F.
Slice bell peppers and zucchini into bite-sized pieces.
Toss vegetables with half the olive oil, half the sea salt, and half the black pepper on a parchment-lined baking sheet.
Roast vegetables for 18 minutes until tender and slightly caramelized.
Season chicken breast with remaining sea salt, black pepper, and dried oregano.
Heat remaining olive oil in a non-stick skillet over medium-high heat.
Cook chicken for 6 minutes per side until golden brown and cooked through.
Let chicken rest for 3 minutes, then slice into thin strips.
Spread hummus across the bottom of a wide bowl using the back of a spoon.
Arrange roasted vegetables and sliced chicken over the hummus.
Top with crumbled feta, fresh parsley, and a squeeze of lemon juice.
