1 In a food processor, blend the feta, cottage cheese, cream cheese, and lime or lemon zest until smooth and fluffy.
3 Spread a thin layer of mayo on both slices of sourdough. Toast in the air fryer at 425°F until golden and crispy. (Alternatively, toast without mayo, or pan-fry with mayo-side down.) Then, spread a generous layer of whipped feta onto the hot toast.
4 Top with thinly sliced heirloom tomato, sprinkle with salt, and drizzle with olive oil.
5 Finish with fresh basil (optional) and serve immediately.
