Gland for Some Home Cooking

Gland for Some Home Cooking is an unmarked quest in Fallout: New Vegas.

Walkthrough
Ruby Nash is a kindly old sort, and if you ask her what she cooks, she lets you know all about her casserole. Tell her you're keen on trying some of it, and she asks how many radscorpion poison glands you have. Assuming the answer is "none," she urges you to go out and find some.

When carrying radscorpion poison glands, Ruby will offer you casseroles based on the number of glands in your inventory. Her dialogue choices when trading provide only the option to back out of the trade or give her 'a bunch'. She will always take five glands (the maximum number possible) in exchange for casseroles if the player has at least that many.
