STEAK NIGHT
Grilled Balsamic-Marinated Flank Steak
Using balsamic vinegar in a marinade for grilled flank steak is a genius move. In just one ingredient, the vinegar imparts tons of complex flavor to the meat while also tenderizing this lean cut with its acid. A dollop of country-style Dijon mustard, some grated garlic, and a dash of paprika balance out the sweetness in the balsamic.

This has completely replaced my normal avocado toast! The beans blend so well you cannot even tell, and I stay full until lunchtime!

Great trick for adding protein without cooking eggs on busy mornings. Added a pinch of red pepper flakes and lemon zest—delicious.
