The Classic Roast Beef and Classic Beef ’n Cheddar each list 23 g protein, but they are not nutritionally interchangeable. The French Dip & Swiss/Au Jus lists more protein and substantially more sodium. Choose the published sandwich that meets the limits you actually care about.
Compare the complete named builds
The Classic Roast Beef is 360 kcal and 970 mg sodium. Beef ’n Cheddar is 450 kcal and 1,280 mg. Moving between those two adds 90 kcal and 310 mg sodium while the listed protein stays at 23 g. The difference belongs to the complete builds; it is not a verified nutrition value for cheese alone.
French Dip & Swiss/Au Jus is 530 kcal, 34 g protein and 2,540 mg sodium. Au jus is explicitly in that source entry. Do not add a second serving of dipping liquid to the recorded total simply because it arrives separately.
Use the right filter order
With an illustrative sodium ceiling of 1,500 mg, the first two orders qualify and the French Dip does not. With protein at least 30 g, only the French Dip of this trio qualifies. Combining those two limits leaves no match. That is a useful trade-off, not a failed search.
Before ordering
Check local availability and the source serving. The table shows sandwiches rather than combinations with fries or a drink. A more filling purchased order may have a different total, and none of these differences measures how much you will enjoy it.
