Sure, here is a Python function that reads a CSV file and returns it as a list of lists:

```python
import csv

def read_to_list(data_file):
with open(data_file, 'r') as f:
reader = csv.reader(f)
data_list = list(reader)
return data_list
```

This function works as follows:

1. It imports the csv module, which provides functionality to both read from and write to CSV files.

2. It defines a function `read_to_list` that takes one argument: `data_file`. This argument should be a string representing the path to the CSV file you want to read.

3. Inside the function, it opens the file in read mode ('r') using the built-in `open` function. This function returns a file object, which is stored in the variable `f`.

4. It creates a `csv.reader` object from the file object `f`. This reader object allows us to iterate over the rows in the CSV file.

5. It converts the reader object to a list of lists using the built-in `list` function. Each inner list represents a row in the CSV file. This list of lists is stored in the variable `data_list`.

6. Finally, it returns `data_list`.
