In a small bowl, mix the mayonnaise, lime juice, dried oregano, dried thyme, and black pepper to make the lime-herb mayo. Set aside.
Spread the lime-herb mayo evenly on one side of each slice of toasted sourdough bread.
Layer the bread with microgreens, deli turkey breast and provolone cheese.
Top with the remaining bread slices, mayo side down, and press gently. Cut each sandwich in half.
To make the chia fresca, combine all the ingredients. Let sit for 5 minutes to allow the chia seeds to bloom.
Serve the sandwiches with carrot sticks and hummus, and chia fresca.
