Here in Malawi, you can't seem to find any Mexican food. Only
recently have we been able to find corn chips and they taste
great dipped in our friend's salsa!
Bring everything EXCEPT the vinegar and onions to a boil. When
it is at a good rolling boil, add the vinegar and onions and turn the stove
off. Let it cool. Pour into jars and store in the refrigerator
for up to two weeks. Ours never lasts that long.
