Meet Elizabeth Dubois. I haven't been able to find much biographical information about her as of yet; it seems like she might have been married to someone in the book trade. I have only heard of her through her advertisements printed in the 1740s and 1750s as a seller of delicious and practical "Portable Soups" all over London.
She starts running the ads in the London Evening Post for what appears to be solid cubes of bouillon in 1744. "This useful Commodity never spoils if kept dry," she claims, "and is dissolved in a few Minutes in boiling Water; and for Gravy Sauce is much cheaper and better than any usually made on the Spot." Apparently, the single-serving sized cubes were the brainchildren of her uncle, the reputed cook to the late Duke of Argyll, invented while the Duke was engaged with wars overseas. But she points out that they are perfect for other occasions ranging from long hunts "when the chace proves long" (you could chew it like a protein bar) to prolonged naval engagements abroad (when the diet of salted meats rendered good English gravy particularly difficult to obtain.)

Before long, she begins to expand her enterprise, selling her products in taverns and coffee shops all over London: from Billingsgate to Westminster, from her own place in Long-Acre all the way to Bath.

Service becomes more and more personalized. After a few years, Du Bois begins to encourage customers to experiment with mixing her four flavors –– veal, chicken, mutton and "gravy" –– to their own personal liking. She suggests adding salt to taste. But still unsatisfied, she decides to take custom-orders beginning in October, 1752. An ad in the London Evening Post proclaims:
"Having been often asked, why I did not make some solid Soups of Venison, this is to inform such who may be inclined to send their own Meats, of what kind soever, with Directions as to what Spice or Herb are approved, may have their Commands punctually obeyed by their laudable Servant Elizabeth Du Bois, at tte Golden Head ... near Long-Acre; where her strong Gravy Soup, Mutton Broth, Veal Broth, and Chicken Broth, may be had in the utmost Perfection..."
Who knows whether her venture succeeded? I never hear of her after 1756. Regardless, Elizabeth Dubois's marketing ploys suggest that conceptions of eating "on the go" changed drastically around mid-century. No longer would bread and hard cheese monopolize the market on portable foods. Moreover, Du Bois wasn't just selling five different types of bouillon cubes. Her use of culinary expertise –– selling something you couldn't get at home –– and her regard for customer choice imply that she was also selling an idea of English convenience to bring to the the most far flung corners of the earth.
UPDATE: Seems like in the 1760s, a guy by the name of John Davis supplanted Dubois' empire with portable soups that were cheaper (4d per soup) delivered to your house, and were accompanied by various types of pastry: ie lobster patties, chicken and ham pies, and sweetbreads. How can you compete with that???
