Okay, I can break it down.

I don't go a week without using: parsley, black pepper, hot red pepper and garlic (if you consider those latter two seasonings and not vegetables).

I don't go two weeks without using: oregano, sage, thyme, rosemary, cilantro, coriander, cumin.

Life would really stink if I could never again get: foenugreek, fennel, ginger, turmeric, cinnamon, paprika, or saffron, even though I don't use them all the time.

Summer wouldn't be summer without basil (Genovese plus one Asian variety, usually). But I almost never use it out of season (including not bothering to grow it in containers).
