I know it depends on what youn have it on - but overall what do you like?
On a bacon sarnie it has to be brown. 
Brown all the way baby ;)
does chocolate count???
Ketchup on chips but salad cream on anything else.
Mayo, best if homemade
or hollandaise but there’s no option to vote for :Wow:
Are you talkin about the topic or something else?
Brown for me all the time.
that’s racist!..
i love my mayo me!.
Red for me
Freak… Mayo is the only way to go… and if you can get it - Miracle Whip from the states is even better!!!
DADS Spicey Brown!
Miracle whip is a wonder of the modern world…
But being a fake canadian id have to say its good’ol Maple Syrup on EVERYTHING!
yup… even the toast, eggs, sausages, toast…
dads for breakfast egg and things…plus a bit of marmite if its a toastie or sarny…
salad cream for any lettuce or cheese or ham based sarny…
Ketchup for burgers and chips
Mayo for tuna…if you must…
Ketchup on egg and chips 
Brown on everything else & Hammonds chop sauce is the Daddy
Mayo all the way
I had chop sause for the first time last year and it is nice.
Enconda Mango Chilli dip on EVERYTHING! omg it’s heaven
Out of the chosen options - brown sauce.
The Enconda sauces are great so can’t answer until they are on the list - The mango one is fantastic with gammon, mustard one great with beef and chops, general hot chilli one works great (as does Tabasco) with chips, chicken, sausages etc. BTW salads are great with pickled red jalapeños.
(I must say the Firefox British English spell checker is really great - it suggested the eñe.)
I repeat… the mango chilli is FAN-KIN-TASTIC on EVERYTHING! Try it on a tuna melt jacket potato… chips, pizza, spare ribs, chicken… drools*
