Finding a vegetarian recipe should not be a problem.
Maybe the very first thing you should try is taking any of your favorite recipes and look for ones that don't contain meat. Maybe it's different in Ukraine but before I was vegetarian there were all kinds of vegetarian dishes I ate each week. Breakfast included things like scrambled eggs and toast or oatmeal. Lunch included things like Peanut butter and jelly sandwiches or vegetarian soups and a roll. Lots of different salads can be made meat-free. And for dinner, there were all kinds of pasta dishes that were already meat-free.
The next thing you should do is look at the recipes and meals you eat now and just take out the meat. Pasta sauces don't have to have meat. Even a sandwich can have the meat taken out. Lots of different kinds of soups become vegetarian by just not including meat. For example Split pea soup doesn't need any ham and chicken noodle doesn't have to include chicken.
There are dishes where you can substitute something for the meat. One of the most popular is substituting tofu for chicken. Any dish that includes chicken pieces can be made with tofu. I had trouble learning how to cook tofu (although it really isn't that hard), so you might want to use a specific recipe for tofu dishes. If you have vegetaian meat substitutes in the store you can buy those and use those instead of things like ground beef.
If your libraries or book stores are still open you should go to one and take out a vegetarian cookbook (or two). you will have lots of new things to try.
We have a recipe section here at the vegan forum. Also, we post what we have had for breakfast, lunch, and dinner. You should be able to get lots of good ideas just from this forum.
There is also Google. Just think of any recipe and then google it and include the word vegetarian in your search. So you can search for "vegetarian chili" or "vegetarian meatballs".
And you can also just google vegetarian recipes or meals. there are lots of good vegetarian resources on line. I'll put a few of my favorites at the bottom.
There are probably some in Ukranian or Russian.
