There is a gravy we can have. Its the Bisto Best in the glass jars, the blue one, pork i think. Its the only gravy i have found that we can have. I use it loads. Normally take a jar with me if eating at In-Laws or mums.
No, it doesn't taste porky IMO. I would struggle to do this diet without it because i LOVE gravy. lo. I use it to make shepherds pie with mince and tastes fab.
Keep an eye out in Asda. Its normally £1.45 a jar, but they keep putting it on offer. I stock up then. lol
