The portobello ceviche swaps seafood for portobello mushroom marinated in lime juice with grapefruit, celery, red onion, baby dill, Roma tomatoes, and salt. This plant-based take leans on citrus and herbs to create the same brightness as a traditional ceviche while using mushroom for a meaty texture. The mix of grapefruit and lime adds layered acidity, and the mushrooms soak up the marinade, offering a tender, slightly chewy bite against crisp vegetables. Vegetarian diners and ceviche fans looking for something lighter than fish often highlight this dish as an inventive alternative that still delivers the expected citrus punch.
