YMMV but my Aldi’s has 1# baby carrots on sale for .49/bag. 1# fits exactly in a quart canning jar, processed 11 psi 30 min. Pints are 25 min.
Easiest canning you will ever do: no peeling no chopping, 1:1 measuring. You don’t have to buy a full box but if you do, there are 24 bags in a box which is conveniently two full canning jar cases (easy stack and store.)
Also 14.5oz tomatoes and also kidney beans are on sale for .49/can
