Macadamia nuts are a specialty item not stocked routinely at Charlotte-area chains like Harris Teeter, Food Lion, Kroger, or Walmart; you'll need to make an extra stop at ALDI or a specialty grocer, which adds real friction to a weeknight. Dubliner cheese, an Irish aged cheddar, is similarly scarce and typically found only at Harris Teeter's specialty section or specialty shops—budget another hunt or accept a pricier substitution. The pesto itself is fast and uses fresh basil (available spring through fall at all major chains), but the combination of premium nuts and imported cheese pushes the cost per serving well above $3, driven entirely by the nut-and-cheese base rather than yield. The technique is straightforward and keeps well refrigerated for 3–5 days, making it solid for leftovers or meal prep.
