Delicious!
Flavor Name: Original, Lemon Garlic, Hot & Spicy, Size: 4 Ounce (Pack of 3)
Absolutely frickin delicious! The size is good for what you get. I use a bag 3 times for salads. Very easy to keep in the fridge and open and close. I think compared to jars and other olives and the quality it is a good price. The flavor is awesome!

Not comparable to the bars
Flavor Name: Chicken Sriracha, Size: 1 Count (Pack of 1)
I often get the chicken Sriracha bars, so I thought this is a more economical way to get that bit of protein. However, these are extremely different than the bars. They are thinner, obviously, and that makes the whole bar drier and... I'm not sure how to describe it, it almost tastes like plastic. Overall, I'll get the bars any day, but these I really can't stomach. On the spiciness side, I think they're pretty balanced. My husband, who doesn't tolerate heat well, likes them, so I'd say they're mild spice. But I personally cannot get over the plastic flavor.

For the chicken go with the bars, not the strips.
Flavor Name: Chicken Sriracha, Size: 1 Count (Pack of 1)
I really enjoyed the larger Sriracha bars, as they were an excellent combo of spicy, salty, and juicy. Bought these strips under the assumption they'd be the same. Not even close. No detectable salt, only the barest hint of spice (you can sort-of get the spice back if you eat a large chunk and chew it for around a minute), and the flavor when you first stick it in your mouth is dry and interrupted by a weird plastic-like taste for the first ten seconds or so. Since it's food I can't return them. At $40 it's an expensive lesson learned. Go with the bars, not the strips.
