Any Dairy Free tips and easy recipes

Probably going to be the most popular answer but...almond milk - changed my life. You can use it to swap for milk in almost every recipe. If you don't like almonds you have coconut milk, cashew milk, soy milk, etc. There's soy yogurt, soy or almond milk ice cream, whipped cream. Vegan cheese slices. Almost every chain coffee shops now carry at least one non-dairy creamers. Sorbet instead of dairy ice cream when you go out. Pretty sure last time I went to the grocery store I found lactose free cow's milk.

I preferred to switch recipes rather than use alternatives, since I liked so few of the alternatives and they tended to be expensive... almond milk and Tofutti's sour cream alternative are exceptions.
If you cook, look at vegan websites for recipes. Zero thought required as to whether or not you can make any of the recipes you find.
If you want prepared meals too, look into Indian and Thai foods. Chickpea curry is one of my favorites (some brands are higher fat than others), and you can put it over rice, top it with Tofutti's Better Than Sour Cream (which my eat-everthing-husband also loves), and quickly add about any bag of frozen veggies you can steam quickly for a complete meal. Vegetable korma is good too.
& hummus replaced cheese in my book while I was vegan. Fresh cilantro jalepeno hummus is fantastic.

Just wrote you a really long reply and it disappeared before posting - aargh!! Will try and recap in brief...

Milk - Koko coconut milk is a good alternative to milk in cereals, tea/coffee and baking, Alpro's organic soya milk is unsweetened, and my personal favourite is Rude Health's almond milk (sadly not cheap)

Yoghurt - numerous soya varieties out there including Alpro and Sojade. Also try Coyo - coconut yoghurt (quite rich and creamy)

Spreads - try the Pure range, or use coconut/olive oil on toast

Avocado and hummus are great for sandwiches/toast if you are looking for alternatives to cheese - try avocado, tahini and a sprinkling of dried chilli flakes or hummus & marmite (yummy, honestly!)

Use soya or oat milk cream in recipes that call for single/double cream and you can use silken tofu or avocado for creamy desserts (sounds weird, but can work!)

If you want a treat, try Booja Booja truffles - yummy, dairy-free (but expensive). They also do an ice-cream alternative made with cashew nuts and agave syrup or you can get Almond Dream ice cream (made with almond milk) in Waitrose (and perhaps elsewhere). Alpro also do quite nice chocolate desserts and custard. Also try Sojade chocolate desserts. Yummy (I think) and not too sweet.

Plamil do chocolate spreads etc and Meridian do amazing nut butters (another great thing for sandwiches and toast).

I have got loads of dairy-free recipes and if you tell me what kind of food you like I can post a few... Or, as someone else suggested, Google - there's so much out there. Even Jamie Oliver has a dairy-free/vegan section on his website. Try Little Miss Meat-Free, Coconut & Berries, Demuth's (veggie but has plenty of dairy-free recipes) or Flexitarian (just a few UK based ones I can think of off the top of my head). Hugh Fearnely-Whittingstall has a dairy-free recipe book called Light & Easy (I think...) and Anna Jones' cookbook A Modern Way to Eat is wonderful. Totally recommend it. Really tasty food. Vegetarian Living is a nice magazine and has loads of dairy-free recipes or suggestions for alternatives.

Hope that all helps!

I like unsweetened almond milk. For a treat I highly recommend Larry and Luna's Coconut Bliss ice cream - let it soften for a few minutes and it tastes just like ice cream. The only alternative cheese I've liked is Daiya shredded mozzarella.
