Big welcome @HerRoyalFattyness! (you'll have to change that name soon though
)
Given the things you like I think you'll find that LCHF really suits you:
Cottage/shepherds pie
Go and have a look at the Bootcamp recipe threads, that are stickied at the top of the Bootcamp topic - there are at least 2 or 3 different recipes for shepherds pie, using celeriac and/or cauliflower mash instead of potato mash
Roasts
^Perfect LC food - as long as you leave out the roast potato, parsnip and sadly Yorkshire puddings!)
Beef stew
Again, perfect - just no dumplings! See the recipe threads for more ideas
Corned beef hash
Faberooni using celeriac instead of potato - and avoiding low fat/lean corned beef
Pasta bake
Not quite so fab. I'm afraid!
Chicken wraps
^You can make different kinds of wraps - one alternative is to use Little Gem lettuce leaves. Or you could make an egg wrap, which is essentially a very thin omelette.
Burritos
See above!
Burgers
Fantastic LCHF food - obviously without the bun. Some people use iceberg lettuce leaves as a 'holder' for their burger
Sausage and mash
Make sure you're choosing low carb sausages; most of the supermarket premium brands are very high meat content so low in carbs (just check the back of the packs for the carb counts. The Black Farmer sausages are very good and very low carb. Instead of potato mash, you could have celeriac mash, cauliflower mash or swede mash - or any combination of those!
Lamb/pork chops, veg and potato of some sort
Perfect but just drop the potatoes and make sure you have FLGV - our very own acronym for Fuck Loads of Green Veg!
