1. Heat grill to medium to medium-high heat. When grill is heated, place hot dogs on grill. Grill to preferred doneness.
  2. In a medium pan over medium-high heat, add oil, onion and jalapenos. Toss in the skillet until onions are soft and begin to brown.
  3. While the vegetables are cooking, prepare your beer cheese. In a small pot over medium heat, melt the butter and whisk in the flour.
  4. Once smooth, slowly whisk in the beer until fully combined. Add in the cheese ½ cup at a time and whisk until melted. Add in the cayenne pepper for taste.
  5. Assemble the hot dogs by placing in a bun, cover with beer cheese and top with cooked onions and jalapenos. Serve immediately.
