Add Tropicana watermelon, Tequila, and a squeeze of fresh lime juice to the cocktail shaker then start shaking for about 30 seconds. If you prefer a frozen margarita then mix in a blender with ¼ to ½ cup of ice.
On a paper towel spread moderate amounts of kosher salt and chili-lime powder. Wet the rim of a margarita or other glass and gently dab and press on a paper towel until the desired amount of salt and chili powder is applied.
Pour margarita contents into a glass and serve over ice. *If desired, toss in a pinch or two of chili lime powder directly into the margarita.
Notes
**I keep a 2 to 1 ratio of Tropicana® Watermelon drink to Tequila, which makes it very easy to adjust the recipe for more or fewer people. Feel free of course to make it more or less strong (my husband prefers a 1:1 ratio and says it still tastes amazing).
