Usually, there is no need to limit protein, it is fine to eat a “normal” amount. Just don’t overdo it with protein. Remember that LCHF is supposed to be a low-carb and high-fat, diet, not a high-protein diet. Read our guidelines for individualized protein intake.
For a standard low-carb meal, you simply remove the carb-heavy ingredients, like rice. You then add some vegetables and some healthy oil or fat-based sauce. But there are plenty of other options.
