My body began calling for very low-carb and raw, so I asked for suggestions and got these, all raw nibble food:
snap peas, snow peas, asparagus, baby carrots already peeled, mixed salad greens, sliced mushrooms, broccoli, celery, fresh peppers, jicama, dikon radish, avocado, grapefruit. (I love 'cherry tomatoes' but dunno if they meet the requirements.) Their flavors are fine for me without special dressings or dips. Sometimes some plain butter and/or grated cheese.

For breakfast I'm mixing cottage cheese, cream cheese, yoghurt, sour cream with unsweetened cocoa powder. This would keep a long time.

What about boiled eggs? If 'deviled' eggs are too much trouble, you could eat them hot with butter and salt. What about make-ahead stuff like egg salad?
