I like to have an easy breakfast some days of tuna, olives, pickles and some cherry tomatoes
Another suggestion: fish. I buy big jars of pickled herring at Costco, and a little really satisfies. Also smoked salmon, love that stuff. Now, since you're dairy-free, you could serve either of those with some diced avocado and tomato; add some fresh dill to the salmon. Boost your omegas, very low carb, yummy stuff. Just had herring this morning, it really sticks with you. Try it out!
