Built on meaty portobello mushrooms and hearty celery-root mash with bold horseradish and cayenne heat, this is a genuinely satisfying whole-food plant-based plate. The coconut butter adds richness but also saturated fat, and two teaspoons of salt across four servings makes this a high-sodium dish — worth keeping in mind.
