Preheat the oven to 400°F.
In a bowl, toss the potato cubes with olive oil, a pinch of salt, pepper, and half of the samosa spice mix.
Spread the potatoes on a baking sheet and roast for about 20-25 minutes until golden and tender.
Meanwhile, season the chicken breast with the remaining samosa spice mix, salt, and pepper.
Sear the chicken in a hot pan on medium-high heat for about 2 minutes per side to lock in the juices, then finish cooking in the oven for 10-12 minutes until fully cooked.
For the cilantro chutney, combine fresh cilantro, lemon juice, garlic, Greek yogurt, and a pinch of salt in a blender. Blend until smooth.
Steam or simmer the green peas until tender, about 3-4 minutes, then drain.
Plate the sliced roasted chicken with a serving of roasted potatoes and peas, and drizzle over the fresh cilantro chutney.
Serve warm and enjoy the fusion of spicy, tangy, and savory flavors.
