Summer means lots of tomatoes this is a favorite of mine, for a quick side dish.
2 Tomatoes sliced
2 TBLS Ketchup
2 TBLS Cider Vinegar
Paprika - I use Penzys Smoked Hungarian
Slice tomatoes and put in a glass bowl or jar, add ketchup and vinegar. Season to taste with sugar, salt and paprika, use a couple good pinches for the most taste.
Chill for up to 4 hours, place tomatoes on torn lettuce of choice, drizzle with remaining dressing.
