Did a quick google and found this recipe. Most of the catsup in the
grocery store has added sugar, but this does not. Tomatoes themselves
are not all that low carb but since it's just a condiment, you won't be
using much:

Title: Tomato Catsup
Scald, peel, and core a peck of sound, ripe
tomatoes. Mash as if for stewing. Season with a
tablespoonful of ground black pepper, half a
teaspoonful of red pepper, one tablespoon each of
cloves, mace, and allspice, and three onions cut
very fine, with salt to taste. Put all in a
porcelain lined kettle to boil, and when the
tomatoes are thoroughly cooked, rub the catsup
through a sieve to get out the seeds and pieces of
spice. After straining return to the kettle and
let it boil until thick as cream. Set aside and
when cold put into pint bottles, filling each to
within half an inch of cork, and pouring in on top
of each a teaspoonful of salad oil. The bottles
should be kept in a cool, dry place, resting on
their sides.
Does not look to be that difficult. :-)
And this much would last quite awhile I would think...
