Today I decided to experiment and grill a roulade. Working with ingredients I had at home, I created this recipe using a butterflied flat iron steak, prosciutto, asparagus, and shredded Italian blend cheese. The meat was marinated in a mixture of balsamic vinegar, olive oil, Italian seasoning, minced onions, minced garlic, salt and pepper for an hour before assembly and grilling. For such a seamingly upscale dish, it went together quickly and easily – and it was enjoyed just as quickly and easily!  Give this dish a try and impress that special someone with your culinary skills. No one has to know how easy it is…  it will be our little secret! Save Print Flat Iron Steak Involtini Prep time:  1 hour 20 mins Cook time…
