Microwave some frozen peas; add olive oil, walnuts, minced shallots, vinegar, and some soy sauce. Chopping up the shallots is probably most of the time, but there are reputed benefits to eating onions more towards the raw side. Soak the shallots in vinegar for a bit to cut down on some of the burn, or cook them for a bit, unless you hate vinegar or really anything else listed here.
Also good is cooking in advance, if you have a fridge or suitable storage: cook up like two cups of brown rice and two cups of red lentils, with some salt and vinegar, which provides flavor, minerals, and preservation benefits. Oil, spices, and whatnot can be added just before eating, and oil in particular makes the containers that much more difficult to clean, so do not add that early in the process. One of these years I'll remember that walnuts can turn things towards brown or purple, so it's maybe good not to add those in early.
