hi! i live in SF. at trader joe's, these items would be priced at - $5 (bread loaf) + $5 (eggs) + $3 (yogurt) + $2 (onions) + $2 (tomatoes) + $1 (jalapeno) + $3 (parsley) = $21.
i'm rounding up on eggs and bread since you might be buying a more expensive variety, and guesstimating parsley because i haven't bought it from trader joe's before. everything else is pulled from my last few shopping trips.
if you're spending $50 on this, i would highly recommend finding a new grocery store.
