VARIATIONS AND SUBSTITUTIONS

• Protein Swap – Not a fan of tuna? Swap it for shredded chicken, canned salmon, or even cooked ground turkey.
• Veggie Boost – Add mushrooms, bell peppers, or spinach for extra color and nutrition.
• Cheese Options – Sharp cheddar gives a classic taste, but Monterey Jack, Swiss, or even a sprinkle of Parmesan can add a new twist.
• Carb Choices – Use cooked rice, quinoa, or whole wheat pasta instead of traditional noodles for a heartier base.
• Creamy Base Alternatives – Replace canned soup with a homemade béchamel sauce, Greek yogurt, or a blend of cream cheese and milk for a richer texture.
• Crunchy Topping – Swap breadcrumbs for crushed crackers, panko, or even crispy fried onions for a golden, crispy finish.
