Greggs appears to have already brought back a Roast Chicken Mayo & Bacon Sandwich in its upgraded sandwich range, announced in May 2025, and it’s still showing on Greggs menu listings in 2026.

What’s known

  • Greggs said on 13 May 2025 that its “favourite sandwiches have been upgraded,” including the Roast Chicken Mayonnaise and Bacon Sandwich.
  • A 2026 Greggs sandwiches menu listing still includes Roast Chicken Mayo & Bacon Sandwich with a current price range.
  • If you meant a specific “chicken and bacon sandwich” variant that disappeared from your local shop, availability can still vary by location and menu cycle.

Best read on the timing

  • The most likely answer is: it’s already back , not something still waiting for a future relaunch.
  • If you’re asking about a different discontinued sandwich with a similar name, there isn’t clear public confirmation in the results I found that Greggs has announced a separate return date for that exact item.

Bottom line

For the chicken-and-bacon sandwich people usually mean at Greggs, the return seems to have happened in May 2025 , and it remains listed in 2026.

Would you like me to narrow it down to the exact Greggs sandwich name you meant?
