Mushroom & Lentil Burgers with Roasted Red Pepper Guacamole & Sprouts

MushroomLentilBurgers2There are days when even a meat-loving fool like myself needs something a little more packed with veggies and a little less meaty. I could never be a vegetarian – things like this, this and this are just too delicious to pass up! – but I don’t eat meat every day. Red meat, in particular, is a very rare treat in my house (I’ve been known to have very intense cravings for steak every once-in-a-while).

I’ve started a new habit when I go out to restaurants: I’ll order a veggie burger but ask for some bacon on it. I know, I know, I’m guaranteed a questionable look from my waiter, but sometimes I crave the substance of a burger but don’t want all that ground beef. Add a little bacon on top and you get the best of both worlds. 

MushroomLentilBurgers1These veggie burgers are loaded with lentils, mushrooms, onions, walnuts, herbs and spices to make them extra flavourful. And, I’ll admit, I’ve even tried making them with chopped up bacon in the patty! Kind of like a faux veggie burger. Whether you opt for the full-veggie or faux-veggie version, they’re a really tasty burger to bite into, especially when topped with some melty havarti cheese, roasted red pepper guacamole and alfalfa sprouts.

Wait… alfalfa sprouts? Yes! I bought them on a whim, more out of curiosity than anything. I mean, I had a rabbit growing up and it ate tons of alfalfa, so why was it sitting in my grocery store? Turns out they’re pretty good! They give a nice crunch and freshness to the burger, kind of like lettuce. You could even use bean sprouts!

MushroomLentilBurgers3I also need to give a shout-out to this pretty special guacamole. As if regular guac wasn’t good enough, I tossed in some roasted red peppers, cilantro and Sriracha sauce for an added kick. Definitely a keeper! I chose a jalapeno havarti, which I highly recommend, but regular havarti will also do.

These burgers don’t have quite the same texture as a regular burger, but if you cook them for long enough they’ll get a crispier exterior. The walnuts add some much-needed crunch, and if you’re up for it, so does some crispy bacon!

    marvelous! yum yum yum… grazie mille for this recipe :) Jasmin gave me the tip. I started stuffing the lentil-burger puree into my mouth instead of the pan since it was just too delicious not to eat it-right-now… until my boyfriend told me it was illegal to eat Hamburgers raw :)
