Tomato and Onion Sauce or Salad is so easy to make, but really tastes amazing. It's called Molho a Campanha in Portuguese, which translates to a sauce of vinegar or vinaigrette. The tomatoes and basil are bright and fresh and the onions are mellowed out in the sweet and tangy vinaigrette. It compliments steak, chicken, fish, veggies, and more!
Dice the tomato and save the juices, placing both in a large mixing bowl. Dice the onion the same size as the tomato or slightly smaller. Also place both in the mixing bowl.
Slice the basil leaves by stacking them on top of each other, rolling them, then slicing them thin. Place them in the bowl with the tomato and onion.
Add vinegar, starting with ¾ cup. If your tomatoes and onion were large, you may want to add the remaining ¼ cup. The ideal amount is to be able to cover all of the tomatoes and onions, so it's more like a sauce. Add the salt, and pepper. Stir and enjoy!
