In a pan (just get the disposable tin for this I promise it's the easiest option!) add the beef, onions, jalapeƱos, bacon, diced tomatoes, velveeta, pepperjack, cheddar, evaporated milk, seasonings, and Worcestershire sauce.
Place on a hot grill & allow to melt together. Stirring occasionally. It should melt in about 10-15 minutes depending on your heat! Serve with tortilla chips and enjoy!
Or you can add all ingredients into a crockpot and cook on high stirring often, one cheese melts, put on warm.
