Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the yellow potato into 1/2-inch cubes and toss with 0.25 tbsp of olive oil, half of the sea salt, and half of the black pepper.
Spread the potatoes in a single layer on the baking sheet and roast for 20-25 minutes until they are crispy and golden brown.
While the potatoes roast, slice the chicken breast into bite-sized strips and season with the remaining sea salt and black pepper.
Heat the remaining 0.25 tbsp of olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes until browned and cooked through.
Add the sliced red bell pepper, red onion, and minced garlic to the skillet, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Stir in the chipotle peppers in adobo and lime juice, tossing everything together to coat the chicken and vegetables in the smoky sauce.
Plate the spicy chicken and vegetable mixture alongside the crispy roasted potatoes and serve immediately.
