That's brilliant that you got a 2 month free pass, you must be delighted. If you lose 2lbs per week you'll be 16 lbs lighter and it won't have cost you a penny. It will get you back on track in no time. I haven't seen the pics of Davina, she has a fantastic figure, I'll have a check on google.
Dairy free is easy enough, Tesco do a range of vegan ready meals in the freezer section with burgers, pies and stuff in them. There's a recipe for vegan cheese for nachos on the Veganuary thread in Chat, it's made with potatoes, yeast and carrots, I'm going to give it a shot over the weekend. I don't want to rely on ready meals too much but they are fairly healthy and if I chuck a bit of salad on the side I don't feel to bad.
Here's a recipe for chickpea soup that is lovely, though I tweak the seasoning as I go along to suit my taste:
225g Chickpeas 1 tbsp ground coriander
1 onion 1 tbsp paprika
60 ml olive oil 2 tsp cumin
2 garlic cloves 2 fresh thyme springs
1.5 litres veg stock 1 large potato
2 carrots 3 tomatoes
2 tbsp coriander salt and pepper
1tbsp tahini
Basically heat the oil in the pan, fire all the ingredients in the pot, except tahini.
Cook for about 40 mins.
Add tahini and blend.
I use dried herbs if you can't find fresh and the tahini isn't essential but it is nice, it thickens it up a bit. It's really nice soup for this time of year.
