Pat the chicken breasts dry with paper towels and cut them into uniform bite-sized cubes.
In a small bowl, whisk together the smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Place the chicken cubes in a large bowl and toss with the spice blend until every piece is thoroughly and evenly coated.
Heat the olive oil in a large non-stick skillet or cast-iron pan over medium-high heat.
Add the chicken to the skillet in a single layer and sear for 6-8 minutes, turning occasionally until golden brown and cooked through.
Add the diced zucchini and sweet corn to the skillet, sautéing for an additional 3-4 minutes until the zucchini is tender-crisp.
Remove from heat and allow the mixture to cool completely to prevent condensation during storage.
Divide the mixture evenly into four airtight glass meal prep containers and store in the refrigerator for up to 4 days.
To reheat, microwave a single portion for 1.5 to 2 minutes or until steaming, or briefly sauté in a pan over medium heat.
