Tuna, Onion and Tomato Burger
2 servings
15 minutes
Tuna burger with onion and tomato is an original take on classic American fast food, where sea notes blend with rich spice flavors. The history of such burgers traces back to culinary experiments with alternative meats, where beef was replaced by fish. Here, tuna transforms into a juicy, aromatic patty enriched with garlic and ginger. A slightly grilled crispy bun provides the perfect contrast to the tender filling. Pickled red onion and fresh tomato slices add a refreshing tang and light sweetness. A sauce made from capers, sour cream, and mayonnaise highlights the depth of flavor. This burger is a great choice for those seeking a balance between rich, spicy taste and the freshness of healthy ingredients, creating gastronomic delight in every bite.
