If you like more heat, leave the seeds and membranes in the jalapeno. If you like less spice, pull them out before mincing.
You can use any cut of steak you like for this recipe. Traditional cuts are skirt steak and flat iron steak, but you could use a sirloin steak as well if needed. The thinner the cut, the higher the heat should be when cooking.
For thin steaks, cook on medium-high heat for 2-3 minutes per side. For thinner steaks, cook on medium heat for 4-6 minutes per side. Either way, you want a nice dark outside on the steak without overcooking the inside.
