I've always had a problem finding a vegan bacon recipe that I could enjoy. Either they were way too sweet from all the maple syrup or entirely too bitter due to the use of apple cider vinegar. Alas, in my darkest hour of vegan bacon failure, I discovered a worthy recipe at Healthy.Happy.Life. (It was also a recipe that took probably less than 10 minuets to make, which is key upon rolling out of bed around 12ish in the afternoon.) I found the recipe a tad too sweet, still, and recommend cutting the amount of maple syrup in half. The marinade is intended for basically only half your standard ounce block of tempeh, but I doubled the recipe without incident.
