Do you have any recipe books ? If so, I would suggest looking through those carefully. Are there recipes which are low carb ? Are there more, which could be adapted ? We make cheese sauce, by using a Pyrex bowl over simmering water (water mustn't touch it) to melt grated cheese into sour cream, single or double cream or creme fraiche. Are you okay with nuts ? If so, try using things like almond flour or assorted ground nuts, to 'bread' poultry or chicken. Could you sub a lower carb root veg for potatoes ? Could you spiralise vegetables instead of spaghetti, for a spagless bog ?
You should find at least some. I mark cook books with LC for low carb, GF for gluten free (husband is) and V for vegetarian (my mother). That way it only takes a glance to find something suitable.
One book I really like is The Dukan Diet Recipe Book. Dr Pierre Dukan got undoctored for promoting his diet. In UK or USA that would be fine if you're in private practice, but isn't in France. The book is gluten free and many of the recipes are vegetarian. Lots of them can be made low carb, merely by using full fat versions of creme fraiche, milk, cream etc and by buying fattier meat and poultry. They aren't complicated recipes, but have a bit of French flair.
Another way of gathering recipes on the cheap, is to go to your library (if open) and spend some time photocopying recipes. If charity shops are open, you may find a whole array of recipe books, including low carb ones eg Atkins, Pioppi Diet, diabetic cook books.
