To create the Tuna and Chicken Combo, follow these simple steps:

1. Prepare Ingredients: Gather all ingredients and dice the chicken breast into bite-sized pieces.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Cook Chicken: Add the diced chicken to the skillet and season with garlic powder, onion powder, salt, and pepper. Sauté for about 10-15 minutes, or until the chicken is cooked through and golden brown.
4. Add Tuna: Once the chicken is cooked, gently fold in the drained tuna, being careful not to break it apart too much.
5. Season: Drizzle the soy sauce and lemon juice over the mixture, stirring until well combined and heated through.
6. Final Touch: Remove from heat and garnish with freshly chopped parsley for a pop of color and flavor.
7. Serve Hot: Portion the dish onto plates or into meal prep containers for easy serving.

These steps will guide you in preparing this protein-packed lunch effortlessly.
