How to make Onions Less Strong
Red onions can often be over powering for some people. If you love red onions but would like them better toned, a simple trick is to cut your onion and then put in water for 10-15 minutes. This helps soften the onion and pull out some of the flavors.
Note about Cold Olive Oil
Olive oil can change consistency in the fridge if you keep your refrigerator super cold – it is, after all, a fat. How fast it happens really boils down to the actual olive oil and what ingredients are in it. Typically this does not affect the taste, however, it can look or seem weird. Simply bring your salad back up to room temperature for 30 minutes to liquefy the olive oil again or only add right before serving.

Tomato Salad Variations
Marinated salads are so good with just red onions and tomatoes, but you can add a few different things to boost up your salads if you like.
- Use any kind of tomato for this salad, including cut cherry and tomato salads. I prefer a slicing tomato or a ROMA tomato.
- Add quartered or sliced cucumbers.
- Like Cheese? Tomato salad goes great with cheeses like crumbled blue cheese, feta cheese, or small balls of mozzarella.
- Try adding a 1/2 cup of Fresh or Grilled Corn Kernels.
- Top with diced Avocado.
- Crumbled Bacon is delicious sprinkled on top of the tomatoes prior to serving.
- Change up the red wine vinegar for other vinegar flavors. Try the original suggestion first, but feel free to substitute the recipe for white wine vinegar or balsamic vinegar in a pinch (This will change the salad flavor too).
