Quickly saute, or steam, the asparagus for just a couple minutes being careful to not overcook. It will cook longer in the oven!
Lay out the crescent roll triangles, & spread 1 tsp Dijon mustard on each - then sprinkle on cheese, then the crumbled bacon. Divide the asparagus spears equally between all 8 crescents, & roll up. Brush on a little olive oil, & garnish with poppy seeds.
Bake at 350 for about 15, or until the crescent rolls are nicely browned.
