Mix all the marinade ingredients together, and pour into a resealable plastic bag with the steak.
Marinade the steak for 8-12 hours in the fridge.
Dice the peppers and onions right before you are ready to cook the steak.
Dump the marinade, and cook steak either on the stove, or on the grill. It should take about 5 minutes per side.
Remove steak to a cutting board, and in the same pan saute the peppers and onion.
After the pepper mixture is sauted, slice the steak into pieces.
Spread a layer of chips onto a baking sheet. Then top with the pecies of steak and sauted pepper mixture. Top with four cups of shredded cheddar cheese.
