I got this recipe about 4 years ago from a friend in a Bible Study group. Warning! These ARE addictive! You can adjust the amount of spice with adding less red pepper flakes, but it really isn't too spicy.
Spicy Ranch Crackers
1 box Saltine Crackers--all 4 sleeves
1 packet Hidden Valley Ranch Dressing
2 T crushed red pepper flakes
1 1/3 c vegetable or canola oil
Place the saltines in a 2 gallon Ziploc bag and dressing and red pepper flakes. Mix up a bit. Add the oil and move the bag around to get everything mixed well. Do NOT shake the bag or else the saltines will break.
I just flipped the bag over and let it sit for 1/2 hour and then flip it again.
