Feta & Guac Toast with Arugula

No Guacamole: If you don't have guacamole, you can substitute it with mashed avocado, seasoned with a pinch of salt, pepper, and a squeeze of lime juice. Bread Alternatives: You can use gluten-free or sprouted-grain bread as a substitute for regular bread if you prefer a different option. More Protein: Add a hard-boiled egg or a few slices of turkey or chicken for an extra protein boost. Flavor Variations: To enhance the flavor, consider adding a sprinkle of red pepper flakes, a drizzle of olive oil, or a small squeeze of lemon or lime juice. Make it Dairy-Free: Skip the feta cheese or substitute it with nutritional yeast for a cheesy flavor.
