Bentgo Salad Container - 54 oz Bowl with 4-Compartment Toppings Tray, Leak-Proof Dressing Container, Reusable Fork, BPA-Free Lunch Box for Meal Prep & Food Storage; Removable Bento Tray (Slate)

It’s not as customizable so may not work for your specific needs but I have this salad Tupperware thing and like it a lot! Usually I do a sandwich or leftovers from dinner or a salad in the main compartment and then some snacks/sides/toppings/etc in the top part. The compartments on top usually fit everything I need, but they are still a bit on the small side so if needed I’ll supplement with a stasher bag for snacks that take up more space. https://a.co/d/04gKxo5l
