Crunchy Fish in triangle shapes (Great for toddlers)

Cut 1/2 pound of tilapia fillets into 12 triangles. Pour a few tablespoons of fat-free milk into a bowl; dip fillets in milk, and then in a mixture of 1/3 cup unseasoned dry bread crumbs and 1 tablespoon dry ranch salad-dressing mix. Arrange the fish triangles on a baking sheet lined with parchment paper, and spritz them with some vegetable oil. Bake in the oven at 450 degrees F. for 8 to 10 minutes, until fish flakes easily
