Truth is, I get most of my "fix" for ground beef by cooking ground beef, straining the grease like hell, and using it in casseroles with rice or pasta and adding veggies to it. Using only a quarter pound patty for the whole thing. Another consideration of regulating my "red meat" intake to avoid gout.
Another thing I do is to make a single tostada without meat as a meal. Refried beans, fiesta cheese, lettuce, white onion and tomatoes with lots of hot sauce on a prefried corn tortilla. I try to eat a few meals each week that are all veggie.
I have a friend with severe cardiac issues (she's had 4 heart attacks) - the same friend who was hospitalized after her cat climbed up her leg like a tree trunk and she couldn't stop the bleeding because she takes so much blood thinner. She steams her ground beef so as much fat as possible drips out. She puts the beef in a fine mesh strainer over a pan of boiling water, covers it with a lid, occasionally stirs it, and cooks it that way until it is done. The fat drips into the water below.
She then uses the steamed beef to make soups, stews, casseroles, etc. and throws away the water. If I still had a dog, I'd get the fatty, beef flavored water from her to supplement the dog food.
