it’s not just “a lot for a salad”, it’s three-quarters of an average adult male’s total daily calorie intake…
There’s no way to link directly to the pop-up for the Grilled Oriental Chicken Salad specifically, but It’s about a quarter of the way down this page) and it looks like it’s not so much the protein that accounts for the massive calorie count (though at a claimed 58 g, there is most of an average person’s daily requirement in there), it’s the 90 g of fat and and 114 g of carbs (including 50 g of sugar !?) Apparently 190 calories of that (from 7 g fat, 25 g carbs, and 5 g protein) is in the “Golden Brown Signature Breadstick”, but even still - holy carp! On the other hand, I do wonder if they served it “dressed” or if the dressing comes on the side, in which case the nutritional info probably covers all the latter that’s “served”, rather than “what’s on the ((main) plate”, or some sort of theoretical average amount of dressing used… And I imagine it is the dressing that accounts for most of the fat and sugar. So if you go very easy on it, you can probably cut way back on the 138% of the RDV of fat and just under 2 ounces of sugar 
included in the calorie count…
(If it’s not, meaning, if that is what’s on the plate as it comes out of the kitchen, it frankly sounds kind of gross. At the risk of “over-sharing”, eating “a lot” of “oily” fat and sugar, but less than 3 ounces and 2 respectively, in a brief space of time would usually have me running for the Little Boys’ Room, especially if alcohol is involved in the same meal - and in general, I have a pretty cast-iron stomach… If I’m going to eat 90 g of fat (and a lot less sugar) at a sitting, I’d much rather just eat half a pound of bacon and call it a meal…
