A Hamburger By Any Other Name...

To use the CSS method, add the following CSS to the advanced section in the theme menu: Theme > Customize > Advenced > Add CSS:
body > div.page > div.page_body > div > header > div > button {
width:60px !important;
}
body > div.page > div.page_body > div > header > div > button:before {
background-color: white !important;
color: black !important;
font-size: 90%;
padding:3px;
position: relative;
top: 40px;
content: "Menu";
}
Once the CSS has been added, be sure to select Apply To Blog to save the changes. The first part of the CSS above specifies the width of the placeholder where the text will appear. The second part of the CSS above indicates the color and background color of the text and also uses the position property to place the text below the hamburger icon. Adjust top:40px to a lower or higher value to move the text up or down. Also, a negative number can be used to make the text appear above the hamburger instead of below. Well, that's the extent of my advice for today. Enjoy.
