Some supermarkets have so many kosher products that they may as well be called kosher supermarkets. Here is a brief list of the supermarkets that will be helpful to you if you are looking for kosher goods (within the range of what is available).
The products that you will find with a hechsher include:
Salad dressings, sauces, mayo, ketchup, cereals, tins of tuna, plant-based milk (almond, coconut, oat, soya etc), dried pasta, peanut butter, jam, pickles, canned beans and chickpeas, crisps, pretzels, microwaveable popcorn, energy bars, biscuits, cake mixes, rice cakes, corn thins, cream cheese, vegan products, frozen bagels (Lenders), ice cream (Ben & Jerrys, Haagen Das), and ice lollies.
These are the supermarkets to look out for:
Union Co-op (to a lesser extent but their organic section usually has some exciting finds)
Hyperama, a popular South African supermarket, has also just opened its doors in Dubai. Many of their grocery items are kosher and show the South African Beth Din's logo.
