This is the closest thing to Domino's Garlic & Herb dip you can get on the high street. Find it in the produce section next to the bags of pre-packed salad leaves, and keep it in the fridge.
Morrisons have also recently launched an own brand equivalent
Asda also sell a bigger bottle (250ml vs 180ml) in the cooking sauces aisle, or similar, that doesn't need to be kept in the fridge, and it's only 75p. They call this one Tangy Garlic & Herb Dressing
and some may prefer it, but I think the refrigerated ones are closer to Dominos.Morrisons
have own brand equivalents for the larger, cheaper, non-rerigerated bottles.
Own brand garlic & herb pizza dip pots - Asda
30g 35p - Tesco
Helmans Garlic & Herb Sauce - 250ml for £1 in Tesco
- more like what you'd get in a kebab house than dominos in my opinion
