Antillean BBQ Sauce

I got this recipe of Jennifer from www.slexip.nl at a nice BBQ this summer. Hopefully there will be some opportunities this year to make this one ! PS slexip.nl has its own google gadget:

Ingredients
1 green paprika
1 onion
15 ml picalilly
15 ml concentrated tomatoes
(lemon juice)

Preparation
Chop the onion and the green paprika and fry them in a frying pan.
Add the concentrated tomatoes and pickles and fry shortly
Add water until the right thickness is accomplished let it simmer for a while to allow the flavours to mingle.
Finish off with salt and pepper + a few drops of lemon juice
