Preheat air fryer to 300 degrees F for 5 minutes. (or heat oil in a pan if frying)
Slice spam patties into fry sizes. Spray inside of air fryer basket with olive oil spray and lay fries inside without overlapping them. (or fry in oil for 2 minutes on each side until crispy)
Cook for total of 12 minutes or so, flipping halfway thru time. If you want them really crispy spray top with olive oil spray the last 3 minutes. (set on paper towels when done if frying)
