Subway Tex Mexan Jacket Potato

The Subway Tex Mexan Jacket Potato costs £9.19 and comes to 620 kcal. That is 122 calories more than the same filling in a six inch sub and £1.40 dearer, which buys you comfortably the most filling version of it.

A baked potato replaces the bread, and most builds in this range include cheese as standard. The filling goes over the top rather than inside a roll, with the salad rail and sauces still available. It carries the highest protein figure of any sandwich on the menu, which is unexpected for something this indulgent.

The filling itself is smoky heat over sweetness, with salsa and sweetcorn pulling against extra-spicy chipotle. The potato is soft the whole way through with a firmer skin, so the texture contrast is inside the potato rather than between bread and filling. It eats with a fork, slowly, which is a different proposition from a sandwich entirely.

It suits a proper sit-down lunch and a cold day, and it is the most filling thing on the menu for the money. The catch is portability: this is an eat-in order, and it does not survive a delivery bag the way a cold sandwich does. Cheese comes as standard on most of this range, and it is a good part of why the floor sits where it does.

The obvious comparison is the Tex Mexan sub, which is the highest protein build Subway sells in bread. That sub costs £7.79 against £9.19 here. The potato and its standard cheese are where the extra 122 calories come from, not the filling.

A jacket potato costs more than the same filling in bread, and it is also the most filling thing that filling can become. On this one specifically, the highest protein build Subway sells is what you are actually buying, and the Jacket Potatoes menu lists every alternative with its own price and calories if you want to compare before ordering.
