In a large bowl, mix together soy sauce, brown sugar, lime juice, garlic, Dijon and cayenne and whisk until combined. Add steak and toss until completely coated, then cover with plastic wrap and marinate in the refrigerator 30 minutes.
Meanwhile, heat a grill pan or grill over medium-high heat. Brush with olive oil and add vegetables. Cook, stirring occasionally, until tender, 5 minutes. Remove from heat.
Lay out a piece of steak and place a few veggies on top. Roll up and secure with a toothpick. Repeat until all steak and veggies are used up.
To same skillet add steak roll-ups and cook until charred, 2 minutes per side for medium-rare.
Garnish with sesame seeds and green onions and serve immediately.
