You can either choose from the huge selection of their signature salads, or if you don't want just a salad you can choose from one of their proteins: chicken (salt/pepper or chipotle), steak, or albacore tuna. From here you can choose to get your protein on a sandwich, as a "hot plate" (with mashed potatoes and simple salad), or just on a simple salad.
Bottom line: there's tons of options and it's so easy to customize according to your own tastes.
There's also a board with daily specials based on what's in season, and they get a lot of their ingredients from the Santa Monica farmers market - gotta supporting the local growers.. ahem, I mean farmers!
And they are SO kind, they even share some of their amazing recipes online here. Thank you Tender Greens! I'll continue to be a loyal fan.
