Instructions

Step 1: Toast 4 thick-cut sourdough bread slices in a toaster or on a grill pan over medium heat until golden and edges are slightly crispy, about 3-4 minutes per side.
Step 2: In a medium bowl, scoop out flesh from 2 ripe avocados and mash with 1 tbsp fresh lemon juice until creamy but still slightly chunky. Season with 1/2 tsp sea salt and 1/4 tsp freshly ground black pepper.
Step 3: Spread the mashed avocado evenly over each toasted sourdough slice.
Step 4: Layer 1 cup thinly sliced heirloom tomatoes on top of the avocado, then sprinkle 1/4 cup torn fresh basil leaves.
Step 5: Drizzle 2 tbsp extra virgin olive oil over each toast and finish with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1 tsp fresh lemon zest for a bright, aromatic finish. Serve immediately.
