Wash the kale thoroughly and drain the excess water. Trim off the tough stems.
Heat the olive oil in a large skillet over medium heat. Add the sliced onion and sauté until it becomes translucent.
Add the thinly sliced garlic to the skillet and sauté for another minute until the garlic is fragrant.
Stir in the diced red bell pepper and continue to sauté for another minute.
Add the chopped tomato to the skillet and cook for about two minutes until it begins to break down.
Add the chopped kale to the skillet and stir to mix well with the other ingredients. Sauté for a couple of minutes until the kale starts to wilt.
Pour in the vegetable broth, cover the skillet, and let it simmer for about 5-10 minutes until the kale is tender.
Uncover the skillet, and stir in the lime or lemon juice. Continue to cook for another minute or two until most of the broth has evaporated.
Adjust the seasoning as necessary.
Transfer the sautéed kale to a serving dish and sprinkle with the almonds for garnish.
